I have been using Pinnacle Studio for a number of years. Started with Studio 9 and purchased the 10 and 11 upgrades...each time hoping that they would fix the bugs that consistently caused my computers to crash. I tried the program on a number of machines from a decent laptop to a relatively powerful desktop. The editing features work relatively well and were not hard to figure out. Unfortunately, all too often all of the editing work was lost in a consistently repeating crash or failure to burn the dvd. I am now faced with the choice to commit and buy a more expensive Mac (which I believe might accomplish what I want more successfully) or try a different vendor. I will NOT buy any more versions of Pinnacle.
