Anyone know of a program that will do this?

I've used Easy Video Splitter V2.01 and this works OK but I've tried Easy Video Joiner V5.21 and it just doesn't work for me.

Has anyone got a recommendation for a simple program that can split and rejoin avi/mpg files and works!

Also, just wondering, does anyone know of any way to join srt/sub files to match the joined video files?
