Movie Joiners

Hey, I'm just looking for a simple movie joiner for any and all formats, I use NanDub for avi, and TMPGEnc for mpeg, but I'd like a couple to link others too who need something simple and without restriction.

Any format, as long as it's freeware, or shareware.

Thanks.. B)

C'mon guys, you must have some suggestions.. someone...

This one has worked for me with every file format, Boilsoft AVI joiner.

search on download.com for honestech :)
