I think I am going to give Mediaportal another go, now that 1.1 final has been finally (after so much time and so many release candidates) released. I had been using Mediaportal as my media center software of choice since about 2007 (back in the 0.2.x days) but recently I had been lured away with some of the shinier features of Windows 7 Media Center.
Although overall I have enjoyed the user experience and polish of 7MC, the frustrations and limitations (lack of good plug-ins, local content, themes etc..) continue to mount. There are a lot of things 7MC is simply great at (series record, intelligently recording at another time to deal with timing clashes, Windows integration, four-foot configuration and so on..) but I think I am ready for a bit more freedom again from my media center.
I managed to acquire, for the price of a nice lunch, a brand new Elonex media center Artisan LX a couple of days back. I was initially very excited because up to then I had still been running my first media center was really just an experiment, built from scratch containing mostly old components I had around my place. A year and a bit on, I am firmly hooked on a PC based PVR system the cornerstone of my entertainment system. It contained an Athlon 2600+ processor with 512Mb of DDR coupled with a DVB-T Hauppage tuner and an 80Gb drive for recordings running the open source MediaPortal software. So as you can see, there was plenty of room for improvement.
This was the first time I have really had a tinker with the Windows Media Center range of Operating systems that Microsoft produce and I went in with few expectations, apart from wanting at least as comparable an experience in terms of functionality and flexibility as I have enjoyed with MediaPortal.
The first thing that struck me was how fickle Windows Media Center 2005 was, even with all the roll ups (essentially what Microsoft call Service Packs for Media Center OS) installed. Wikipedia sums up the ‘capabilities’ of WMC 2005:
‘Media Center originally had a limitation of 1 analog tuner, but was raised to 2 analog tuners with Media Center 2005. With Update Rollup 1 for Media Center 2005, support for a digital tuner was added, but an analog tuner must still be present for the digital tuner to function. With Rollup 2, up to 4 TV tuners can be configured (2 analog and 2 HDTV). All the tuners must use the same source, for example they must all be off an aerial or a set-top box using the same guide data, you cannot mix Sky Digital and DVB-T for example.’
XP Media Center really shows its age here – I do not watch any analogue transmissions, so for a Media Center to require a legacy piece of hardware just to be able to access DVB (digital) seems preposterous. But that was not the worst thing! Windows Media Center 2005 is not capable of pulling EPG data OTA (over-the-air) instead requiring an overly elaborate system that relies on a permanent, always on Internet connection. This also raises some privacy concerns as ‘anonymous’ data, which is not entirely anonymous as Microsoft asks for your postcode during set up, is fed back to Microsoft which can include recording / watching trends and general EPG usage. Hitherto my media center system has not been networked. Considering it is in the opposite corner of my house, and I do not stream my recordings or have formal media shares, I never felt the need to network it. It was nice to just have a static, secure system without any security programs or periodic updates – now security monitoring of my media center has been added to my list of digital chores.
None the less, I was determined to give it a fair go, so I added a wifi adaptor, added some plug-ins and configured everything. After spending eight hours getting everything working, playing around and testing… I went back to my custom build. Not all the problems can be put squarely at Microsoft’s feet however. Elonex declared bankruptcy shortly after launching this range and the malicious part of me can see why, if this mediacenter is the sum total of their expertise.
Whilst the case looked rather nice from the outside, the hardware and the design of the internals is what really lets it down. The only element Elonex got right was the noise (or lack thereof) – the media center barely gives out a murmur when idle due to only a since fan which is housed inside the power supply. It runs at 690rpm, which draws air over the CPU heatsink (which has four heat pipes) and directly out the side of the case. However, I stressed ‘at idle’ before for a reason. When the media center does anything the incredibly noisy hard drive starts very audibly clicking and crunching away and it completely lets the machine down.
However that’s not the worst thing about this mediacenter. Due to the fact that there is only one very slow fan the airflow in the case is restricted to circulating around the motherboard tray, the processor then out the power supply. The harddrive and PCI / AGP cards are completely neglected. This point was slammed home when the harddrive consistently reported temperatures of high 50s to 62 degrees Celsius!!! Worse still, when I idled the system, that heat didn’t dissipate. The hard drive is locked into place with a pretentious plastic locking mechanism which neither improves the accessibility of the drive bay nor decreases the vibrations from the drive. There is no thermal (or thermally viable) contact between the hard drive and the case and as such, the hard drive is left smouldering away with no way to cool down predictably with next to no drop in temperature. There is a valid point that maintaining electronic components at a set temperature prolongs their life by avoiding constantly repeating thermal differentials (i.e. heating and cooling) however the fact remains that 60+ degrees centigrade is far too hot for a hard drive. Although my brief research on this did not yield any definitive threshold, most sources agree that 50-55 degrees Centigrade is about the absolute maximum recommended operating temperature.
Couple this practically zero thermal conduction with a lack of airflow and you have a recipie for a very short hard drive life. Even worse, this thermal issue was not limited to HDD, the south-bridge and GFX heatsinks were equally poorly cooled and get unpleasantly hot to the touch.
Worst of all, it is just slow. CpuID and the BIOS disagreed with each other about the exact Intel processor that powers the system. I believe it to be either an Intel Pentium 4 530 (at 3.06Ghz) or a Celeron D 345. There is no way the much older Athlon 2600+ processor with the same RAM should be out performing this setup and yet it does so without breaking a sweat.
All in all, very disappointing. A remarkable demonstration of technical ignorance on the part of Elonex. But hey, I didn’t pay for it and now I have an extra DVB-T tuner back in my original, self built machine.
Design (cosmetic) : 8/10 - Pleasing, with a nice Hi-fi look.
Design (technical) : 2/10 – Poor components poorly arranged.
Cooling : 6/10 - Great CPU and powersupply cooling, but everything else is woefully neglected.
Acoustics : 6/10 - Silent until it has to touch the harddrive, still a good effort though
Connectivity : 8/10 – Lots of connectors for digital Audio and Video
Capacity : 5/10 - 200Gb harddrive with a portion taken for recovery. I wouldn’t trust it though and by modern standards it is rather anemic.
Overall : 2/10 – Great for free, if I paid anything for it I would have been annoyed.
Whilst it seems the Internet enjoys a good Microsoft Vista bashing (see previous post on topic) research today came out suggesting Windows 2000, an eight year old operating system that recently entered long term support phase by Microsoft, is more ‘secure’ than Windows Vista. (Cue fanboy and antiboy posts.)
But this is rather misleading, let us not forget, Windows 2000 was released in February 2000, a dark era where firewalls, security software and Windows Update were treated with suspicion previously reserved for black magic. Ok, so maybe I am exaggerating slightly, but back then the average PC had either a Pentium 2 or 3 processor between 600Mhz – 1.2Ghz, between 32-128Mb of RAM and a 20Gb hard disk and was aimed at the business market not consumers who had the privilege of running Windows ME (let the justified ME bashing commence.) But we are still missing the point here, now the only users that run Windows 2000 (which accounted for about 2% of all Internet traffic in March 2008 ) are those who are comfortable power users (like Steve Gibson) or those with old hardware (e.g. Third world etc.) As such, it is not worth the malware authors’ time to target such a small percentage of the userbase when they are more likely to snare the vulnerable XP or Vista users.
Worse still, serious doubts have been raised over the validity of this study given PC Tools did not scientifically determine the states of key security within the operating like Windows Vista’s UAC or even which service packs were installed on the computers. As noted by Ars technica, often the first action by typical malware is to download the target package(s) onto a system immediately after it has been compromised with the usually relatively small initial exploit. This could mean that their numbers are greatly misleading when three or four ‘infections’ could actually be a single instance of malware.
The only way to scientifically conduct such a test, would be with three virtual machines, one running Windows 2000, one with Windows XP and finally one with Vista each running a with a comparable set of security tools and the latest patches. That way, after each exposure, the virtual machine could be examined to determine if the exploit was successful and if so, the degree to which the target machine was compromised. At the end of the experiment, the virtual machine is ‘switched off’ without writing the changes to it’s virtual disk and restarted to test the next exploit. Using this methodology, all exploits can be tested equally and methodically and various configurational permutations can also be tried (e.g. Operating systems with only default security measures etc.)
Let us also not forget, there is no way to tell whether these threats are serious silent drive by download style exploits (which would constitute a serious threat) or as a result of user ignorance which even the most secure operating systems and security applications can not guard against. Playing Devil’s advocate, I can see a case that unscientific tests like these better represent real world conditions, however it can not be used to judge to reliability or security of Operating Systems nor the users using them as no conditions nor variables have been made constant. As such, unfortunately, these results have no validity as far as I am concerned.
