DirectX video(movie) display issues

[quinriva]

For some reason or another I get a black screen when I run any video. Audio is fine.

I used Media Player Classic, VLC and Windows Media Player (most recent version of all).

Disabling DirectX fixes the problem, but it is a pain in the arse having to constantly disable and re-enable it all the time.

Note, that videos running in Firefox seem to run just fine (2.0 beta 1).

I’m pretty sure it is either one of two things:

directx_apr2006_redist.exe or the new nVidia drivers.

BTW this is not a general directx issue with SP1 on Win2003, games and stuff work just fine.

Anyone know what’s wrong or how I can fix this?

Relevant specs:

Windows 2003 SP1

Forceware 91.31

Opteron 165

DFI LanParty UT SLi-DR

Geforce 7800GT
