I have a ATI HD2600Pro card. I can't get hardware acceleration to work with VMR9 (renderless) at resolutions higher than 800x600 (not video resolution). It works fine with VMR9(windowed), but then I can't use subtitles in MPC-HC. I can see that HWA is active since CPU load is low, but the videoquality is horrible and then I get a blue screen with a graphic driver error. I can use VMR9(renderless) With the cyberlink codec and zoomplayer, but the video stutters so I'm not happy with the quality.
Need som help here....

(I have the latest drivers and latest versions of the players and codecs)

too many reference frames or b-frames.
check the MeGUI DXVA profiles.

Installed MeGUI and set B-frames to 0 and reference frames to 1. Still same problem. Tried both MPC home cinema and zoom player.

go get a apple hd trailer to see if the file is the problem, they plays ok with my hd2400.

i still recommand you double check your driver, i got definetly the same problem as you described above while i'm using Vista stock driver, later i upgraded the driver to Catalyst 8.3, the prob is gone.

Ok, apple trailer works fine in zoomplayer but not in MPC-HC with VMR9(renderless). Also tried the Haali renderer, but it seems like it doesn't use DXVA?

I will try to reinstall the graphic driver as you suggested.

Guess I have to give up then. Use CoreAVC and fry burgers on the CPU heatsink.

I have changed both reference and B frames with MeGuI. Still same problem. Does the MeGUI setings apply to all players?

Reinstalled windows and the drivers. Only installed MeGui and MPC-HC and no other codecs and players, still same problem.

The MeGUI setting applies to whatever you encode with it. If your file has too many refs for dxva the only thing you can do is reencode.
