The one I use and prefer for the most part is Ulead media studeo...its not cheap though.  FOr a budget, Ive heard good things abour Video Explosion ($70 or so) avail at Compusa and BB
STAY FAR FAR FAR FAR FAR FAR FAR FAR away from Pinacle.  Its the crash master.  Ive loaded it on 3 different computers with diff Mobo, Intel/amd cpu and 3 diff makes of video cards and sound cards...they ALL CRASH with a regulariety that makes Battlecruiser 3k seem stable.
