Resolved CODEC problems ??

I have four old .avi files which up to now in XP Explorer have displayed the first frame as a thumbnail. Now three of those files have only a simple AVI icon instead of the thumbnail, and in my video editor they have a marker indicating wrong or missing (audio?) codec, which will play but with no audio.

I also use the WinAVI video converter which has always worked before but now results in files with the same problem.

If I play those files with Windows Media Player there is no audio, and in my Video Editor I get the video track but no audio track and if I ask it to select a codec it says there aren't any suitable. Also, if I use WinAVI to produce a .wmv file it is complete with audio.

This seems to suggest a problem with Windows, but what?

 

Many thanks Evan. I've just been flogging away reloading old backups, to no avail. However, I have followed your advice exactly, and BINGO!! all problems solved!! I had difficulties working out which was the true download and which wasn't, but I got there in the end.

There's nowhere like WindowsBBS for fixing problems!! Thanks again.
