Check out Serif MoviePlus. I have Pinnacle studio9, Ulead6, MovieMaker and
Serif MoviePlus. MoviePlus has unlimited video and audio tracks and version
5 is easier to manage the timeline.
Pinnacle has an option to purchase a key to unlock one more video track for
a price and lousy support. I had it for 2 years now and am still waiting for
an answer to a question I posed when the render process wouldn't finish on
anything I ever did in Studio. Ulead is not bad, I use it for certain
things, but I'm not sure about the extra tracks in it.
You can try older versions of MP, but don't do any older than ver, 4....
MovieMaker is a fun learning program, but too limited for serious editing of
large files.
