Maybe most of the users use a 3rd party video card (ATI / NVIDIA) and not the poor onboard solutions and don't have probs with DXVA/2.
ATI should be your first choice for an HTPC.

On my new HTPC I got video corruption when DXVA2 is enabled.
Video playback is just fine with DXVA2 disabled and "Adjust display refresh rate to match video" enabled. I got perfect 24p output.
Specs:
Core i3 2100T sandy bridge
Asus P8H67-I (mitx)
Win7 Ultimate x64
Intel driver: 8.15.10.2219 (because all newer versions give me a bsod when connected through HDMI on my Samsung plasma tv, it's an intel/asus problem that still hasn't been solved.)

Highly recommend using an nvidia GPU.
They tend to get more support than ATI.
In fact to get an ATI GPU made after 2006 (Acquired by AMD) you need to buy an AMD Motherboard, No PCI or GPU port versions after that year

Pentium G6950 (of the i3 family really, the smaller cousin of i3-540) has bad video problems with DXVA2 (often fine but just as often extreme stuttering, pixelation, and strange colors). MKV/x.264+AC3 file downloaded from somewhere, made by very experienced ripper.. Works nicely without DXVA2 (and also in MPC-HC with DXVA via MS-DTV codec, I wish I could use that in XBMC; the internal DXVA/h.264 codec in MPC-HC is also crap but exchangeable).
Solution is to switch off DXVA2. Since XBMC consumes 20% CPU idle and 15% when playing an SD h.264 rip, the idle consumption most often is more of a problem anyway.
I don't think the statement "Hardware-accelerated playback of H.264 material was fixed today in ffmpeg for Intel GPUs (patch originally from VLC..)" holds water. Besides, VLC never had any HW acc support, only "experimental", which I tried and that sure doesn't work. The only 3 codecs that work on i3 etc are MS-DTV, DivX and Cyberlink. Since they are proprietary I suppose the can't be included? But MS-DTV is already present on Win7 machines, couldn't you make it use this if it's already on the PC? Don't know why you necessarily must come up with your own codec when it's already preinstalled and for free on 9½ of 10 PCs.
Edit: also tried an i3-540 CPU now, same problem with DXVA2, but CPU usage is down to 5%.

Hi there thought of opening a new thread but Google hit this one so here goes:
I recently picked up an itx G45 board + E5200 chip on the cheap in a flea market and decided to slap up a SFF HTPC for one of my rooms and actually it has been fairly decent if i set render mode to software and disable DXVA2 in Frodo/Windows 7. My question is - the current TV is 720p only but what if i get a 1080p TV down the road
1. Would the above solution work fine for 1080p?
2. Is there a fix/beta drivers/etc to enable DXVA2 with the G45 IGP?
3. Would assigning everything to play on MPC-HC be an alternative to #2?
