Problem playing AVI file with Windows Media Player when us..

Archived from groups: rec.video.desktop (More info?)

This is very strange.

I am using Azureus as my bit-torrent client.
I downloaded a set of AVI files.
I tried to open one of the AVI files in Windows Media Player 7.x by
clicking on it within My Computer.
Windows Media Player gave me an error saying the file wasn't support.
I installed GSpot and it cannot identify the file. (ie: it says "Not
an AVI file" ).

Now here is the WEIRD part of this...

If I go into Azureus and I double click on the file, it opens up fine
in Windows Media Player.

Has anyone seen behaviour like this before?

thanks,
Steve
