Sound but no picture

I’ve recently installed Wondows XP Home on a new PC and installed Windows Media Player 10, the XviD-1.1.3-28062007 codec and the XP-Codec-Pack-2.3.4. My avi movie files are playing with sound, but no picture. Any idea how I can correct this?

Download and install VLC and see if they play…

I’ve sorted it now. It seems that if you untick the “Use Overlays” box in the video acceleration properties, that does the trick.

Thanks anyway.
