Messugga, tx for the hint on checking the acceleration, will for sure check it out. Is it a Win-XP or XBMC setting?
No problemo. It's a XBMC setting. I run XBMC Live so my settings are slightly different to yours, but have a look
here. I see
mention of that option not being available under certain version of Windows.
From the
official XBMC wiki: "Hardware video decoding via DirectX Video Acceleration [70][71] is now supported although this enhancement currently only runs on Windows Vista and Windows 7 due to the author's currently using the DXVA 2.0 API which is not supported in Windows XP.[72]", so it seems you're out of luck if you want to use XBMC on Windows XP. That being said, Windows 7 scales excellently and runs fine on even Atom-powered netbooks, so although performance won't be stellar on the MicroServer, it would be an easy solution should you insist on going the ATI route.
If, however, you insist on using XP,
this is an option for you. Personally, I don't like hack jobs like this and would prefer to avoid it if possible.
Ps. The GPU I purchased from Prophecy is as follows:
1 x Innovision N210-1DDV-C3BX NVIDIA GeForce GT210 512MB DDR3 64-bit A43_N210-1DDV-C3BX R338.13 R385.47 R385.47
It doesn't come with a LP back plate, but that's not a big deal to get around.
