Anyway, back to your problem. Chances are your pc is underpowered. WMV9 is a very processor-intensive codec and will drop frames/play video out of sync on older processors. There’s not much that can be done about this. You could attempt to allocate as much resources to video playback by closing all unnecessary background tasks (instant messaging, file sharing, any icons in the system tray, etc). |
