You da man !
BTW, I have a testfile here (.mp4) rendered straight out of Sony Vegas Pro 13
which makes VD preview window exhibit a horizontal pixel shift of x:=(x+2) per line, but only if VD window has focus.
If a different window obtains focus, VD windows shows correct preview. The same source decodes in MPC-HC, MPC-BE under LAV fine.
Win7U64 SP1, nVidia Quadro K5000M, driver 372.95
Affected: 40539, 40463, 40464
Not Affected: 40538...
Eek, thats fishy: The same version can work and not work. I happened to hit F1 and the behaviour changed. Gah.
Maybe my side again ? Unfortunately the other systems are out of reach now. The svml_dispmd.dll window came back.
Interference on my systems side, but by whom ?...
