How to tell format?

[foreveryoung]

Let's see... there's XviD, DivX, 3ivX, MPEG-4, AVI, etc., etc... I don't think there's a file extention per format.. How do I tell what format a movie file is in? Could poor playback of a file be a result of one player using the wrong codec for the format?

In order to determine which codec(s) you need for a particular .AVI, you should do the following:

1) Load the .AVI file into VirtualDub (or one of its many variants) or NanDub

2) From the "File" dropdown menu, select "File Information"
