Whoops.... I just found out there's a similar thread about this... My problematic video is also from a video camera, so it's probably the same problem... =\
My Winamp 5.02 crashes whenever I try to open a certain AVI file with it. I don't use any third-party plug-in. I'm using a classic skin. I'm running Windows XP on a 630MHz Celeron with 128MB of RAM. The AVI file is 3.10MB and plays fine on Windows Media Player 9. Winamp works well otherwise.
Right, so if you need anything else I'll be glad to help.
And if this is known or I ignored some rule or something, I'm sorry in advance.
