I've tried Pinnacle Studio9 and Ulead7. I now use MoviePlus4 almost
exclusively.
I particularly like the ability to add unlimited audio and video tracks. Of
course, over time I have learned more, so the difference is not all program,
But i seem to edit my home movies a lot quicker and get lots better results.
I never could get Pinnacle to work properly, and they never even
acknowledged my emails to support. Ulead was ok, but I had a limited version
and didn't like that.
