WinDVD 9 Blu Ray Picture

[Willzihang]

When I try to run Blu Ray titles in full screen my image is overly pixelated, as if there is some kind of filter or scaling going on - almost like it is applying a standard def DVD filter. I have looked through every option to no avail - I have attempted to disable hardware acceleration (I am using a HD 2900 XT) but when I continue playback and go into options again it has re-enabled itself. I am unable to change or alter any advance video settings/enhancements, presumably because I cannot turn off Hardware acceleration (though i doubt this the the reason for the problem as PowerDVD had Hardware acc. on and the picture was fine)

I am using a 24" screen at 1900x1200 res, PowerDVD Ultra runs my blu ray discs in full screen using the same desktop res and everything perfectly sharp without this problem, so it must be something to do with WinDVD.

Incidently my blu ray drive is a Pioneer BDC-202BK.
