Windows 7 Media Center (7MC)

I have just upgraded the Intel Atom based machine that I have being using to run Vista Media Center. I connect it to my TV using the Linksys DMA2200 Media Extender. The combination works a treat although occasional the Media Extender does need to be rebooted. This set up is described elsewhere on this blog, but I think it is fair to say that running Windows Vista on such a small footprint machine is pushing the limits (1.6GHz HT processor with 1GB of memory).

Well, I thought I would push the limits a bit further and install the Beta build for Windows 7 onto the machine. I am using the Beta build (build 7000) that was released last week and you can download off MSDN.

I did an upgrade from Vista SP1 using the ISO download on a DVD. The process is fairly seamless and can be done completely unattended, except the bit at the end where you need to insert the license key. Amazingly, it came up first time without any problems. Not bad for a Beta! I have included the performance data above. You can compare it to the results from Windows Vista here running on the same box.

OK, so onto Media Center. First time you start it up, it asks if you want to import that previous Media Center. This is what I did and it worked well - it sorted out the tuners (the drivers all worked), it re-tuned the tuners and even imported the existing scheduled recordings. The Media Center UI has been revamped in Windows 7 and it looks a little more polished with some additional features. As always, it is going to take a little time to get used to. More of this once I have had more time to play with it.

I powered up the Media Extender (expecting to have to set it back up again) and it worked first time without any fiddling or re-setting up. I hadn't really thought much about it, but I was pleasantly surprised when the new Windows 7 Media Center UI appeared on the extender. Cool.
I do seem to be suffering from some more network connectivity issues than I have had in the past. But I can't see how this is due to the new version of Media Center. But let's see how it performs over the next week or so.

Intel Atom Media Centre (again)

The Intel Atom Media Center seems to be working well with the Hauppauge Dual Tuner PCI card. It seems to have enough CPU to be able to record 2 channels while playing back a previously recorded programme. Indeed, looking at the performance of the machine shows that this is only using around 15% of the CPU. Overall, the unit is pretty quiet and uses only about 35-40W.

I am using a Linksys DMA-2200 Media Extender to stream TV (Freeview not HD) over WiFi to my TV. The Media Extender outputs 1080i format and is connected via HDMI to the TV. This essentially means that the extender is upscaling the image for display - the unit includes a DVD player as well as the Media Extender (this enables the playback of DVDs which cannot otherwise by played by the extender. The unit works reasonably well, but is a little short of horsepower - this shows up most of the animated Media Center user interface. You can customise the user interface not to use animation, if you want. This improves the responsiveness of the unit.

While this works technically, it isn't a great solution. It is far too expensive. The Linksys DMA-2200 retails for around £200 which makes it more expensive than an Xbox-360 which also plays DVDs and works as a Media Extender (it plays games too and is £40 cheaper!). The only advantage that the DMA-2200 over the Xbox-360 is that it is quiet. Then once you add in the cost of the Media Center, it all gets a bit ridiculous.

Since the Media Center is on all the time (to "hoover up" those TV programmes), I have decided to use it as a Print Server too. It would be really neat to see the Media Center capability built into Windows Home Server (you know the one that provides backup, file serving and remote access. This would mean taking all of the "Services" that should be running all of the time and combining them to run on a single (highly efficient) hardware platform.

Intel Atom DG945GCLF Motherboard

Just built a mini ITX PC using one of these motherboards. The motherboard has one of the Intel Atom processor onboard (230 clocked at 1.6Ghz). Probably the most remarkable thing about this processor is its power consumption of around 5W. The motherboard does have a fan, but it is on the graphics processor and not the CPU.

The motherboard was bought from Tranquil in the UK and set me back £42 (excluding VAT and delivery). I fitted it into a Noah 3988 case with a 500GB 7200rpm SATA drive, 1GB RAM and a slimline format CD/DVD drive. It is powered by an external power block and DC-DC board.

This combination is very quiet and produces so little heat that I could probably disconnect the fan in the case, leaving just the fan on the graphics processor.

I installed Vista Ultimate onto the machine. It installs without any issues and the CD that is supplied with the motherboard contains all the relevant drivers. The CD even recognise that it was installing on a Vista machine. The aero UI on Vista came up first time with the drivers on the CD. The network also installed without any issues. The audio took a little more fiddling with to get it to work.

The screen capture above shows the performance figures that I got out of the machine once I had installed the drivers from the CD enclosed with the motherboard. There is a definite improvement in video performance with these drivers - the graphics increased from 2.0 to 4.2 and the gaming graphics increased from 2.4 to 2.8.

When running Vista, this unit is pulling between 30-40W (most of the time it runs at about 33W). Exactly the same configuration with a D201GLY2A motherboard (Intel Celeron processor running at 1.2GHz) pulls about 40 - 50W (averaging around 45W). Because the Intel Atom is generating less heat, I unplugged the internal case fan. In hindsight, this was pretty pointless - it saves about 1.5-2W and makes very little audible difference to the running of the unit.

With this configuration, this unit is pretty quiet and would make an ideal candidate for a small format Vista Media Center. However, the motherboard's very limited video output capability (a single VGA connector) probably limits it's use in this department. Personally, I have been using the Linksys DMA-2200 Media Extender to connect to my TV via HDMI. So the lack of video connectivity is less of an issue.

I have a Hauppauge Dual Tuner TV USB stick that I will put into this machine and test out in the next few days.

Installing Windows Vista on a MacBook Pro

My current laptop has run out of horsepower. I put some more memory in it last year, but it is now up to it's limit - 512Mb. It is only of the small Sony Viaos (Sony TR1-MP). I guess it is coming up for 3 years old so it is no surprise that it is time to replace it.

I had a look around and really liked the look of the new Apple MacBook Pro. Of course, these are Intel based and it is relatively straightforward according to some colleagues that have done it.


It took me a while to track one down - I was after a 2.4GHz, 15.4" MacBook Pro. Eventually, I found on in the Apple store in Brent Cross shopping centre. It was interesting that everyone else seemed to be sold out except the Apple Store. The price was pretty much the same wherever you bought it.

It is indeed quite straightforward to set the MacBook up to dual boot. You need to download BootCamp from the Apple website (http://www.apple.com/macosx/bootcamp/). The software is Beta, but seems to work a treat. I used the latest version of the software - 1.3. The trick is to print out the instructions and follow them (http://images.apple.com/macosx/bootcamp/pdf/Boot_Camp_Beta_Setup_Guide_v1.3.pdf). I was installing Vista Ultimate and the installation went without a hitch.

I have got everything working except the I-Sight camera. As part of the Boot Camp process, a set of Apple drivers are copied onto a DVDR and installed after Windows has been installed.

One of the cool things about Vista is being able to review the performance of the computer and its components. I am really impressed with the performance of the Mac Book (I have included the snippit from the performance monitor). It is way out performing my Toshiba M400 laptop that I use for work as well as my home desktop machine.

Pretty impressive for a laptop! And it is dual boot so now I can run Aperture too!
