video splicer
 

I remember there was a software tool that allowed you to piece together videos that had been broken up so that all the pieces would play together with out interruption.
I was wondering if anyone remembers what it was called, or where I could find it.

Thanks

Probably there are many, I have used this one (Simple File Joiner) Peretek, Inc. - Home Battle Vaughan

For video files in an AVI container VirtualDub has an "append avi segment" function that works well in conjuction with "direct stream copy" (no re-encoding).
