VirtualDub + Mod help - Joining files.

[Fukushuu]

I'm trying to join 2 files together but when I do an error message comes up saying "The video streams have different data formats".

What does that mean, and how can I fix it so I can join the files.

Don't post twice. If you haven't had a response in 24 hours, bump once. If you still don't get an answer, live with the fact. There is no obligation on anyone to answer any given question, and sometimes people just don't know. But if you drop the same question multiple times you will just annoy people, and no-one will answer you.
