Help! Video playback problems!
Help! I have run out of options here, I'm hoping one of you has some idea what could be causing this.
I suddenly started getting video playback problems on my PC. The video file starts playing, the audio is there, but the video screen is blank. I'm not getting an error message, and the player is sizing itself to fit the size the video should be.
This happens to all sorts of video files (.avi, .wmv, .mpg) and in each of the three players I've tried (Windows media player 9, Media Player Classic, and VLC). The video files have worked in the past (today!) with this video card and this monitor.
Oddly enough, Quicktime works fine, as do embedded YouTube videos. Everything else is working fine, including some fairly graphic-intensive games.
The only potentially relevant thing I did between the time video worked and the time it didn't was install an image viewing program called ACD See. I have no idea if this is related, but I have since uninstalled it anyway.
Here's what I've already tried by way of troubleshooting:
Adjusting the screen resolution, colour quality and refresh rate
Running dxdiag (directX and directdraw test fine)
Reinstalling the latest nVidia drivers
Reinstalling the various divx codecs
Reinstalling VLC
Installing the latest version of DirectX 9.0c
Rebooting.
The most recent thing I tried doing, pretty much in desperation, is disabling DirectDraw acceleration in dxdiag, and that worked. As long as directdraw acceleration is disabled, video files play OK. But I never had to do that before, and it's a workaround rather than a solution. There are a lot of things on here that I need directdraw acceleration for!
Does anyone have any idea what could be causing this problem and how I could fix it?
