Need help with an AVI

[JimmyW]

I just gave TrID a try, and it promises to be quite useful!  I'm stumped, however, on one file.  Its extension is AVI, and it plays fine in any common viewer.  The header is not a standard AVI signature, and I've been unable to find the file type that matches the signature.  The first eight bytes are 0x96924E52A5CCC90F.  Thanks.

Hi!

It's surely isn't an AVI file, but probably common enough to be recognized and played anyway.
Maybe you can post a bigger dump using MiniDumper, and also try to se what GSpot think of that file.
In addition to that, if the file is playable by VLC, it can surely provide some info about the kind of stream it's playing.

Thanks for the feedback,
Bye!

Thanks very much for the suggestions.  GSpot and VLC report that the CODEC is MPEG-1.  The header isn't standard for an MPEG.  The first 256 bytes are as follows:
