Welcome to the forum.
In the first linked artilce in John T's reply, the one discussing AVI as a wrapper, there are some links to utilities to "peek inside the wrappers," and the results from either G-Spot, or MediaInfo, will likely tell the tale of why your AVI is not behaving correctly. If you could post that info, someone can possibly help.
I will do some of the suggested research and give it a try. Thanks.
Yes, please report the full specs. of that AVI file. If you use G-Spot, probably the easiest way to do that (saves a bunch of typing), is to just post a screen-cap of the G-Spot screen. It will contain all of the info.
