I did a search and nothing helpful appeared so here it is. These questions may be dumb! Quick Time Pro: 1. Does this enhance the video quality of viewing video files like trailers, other types of mpegs etc...? 2. When you get QTP, are you able to download large trailers that are otherwise restricted? 3. Is is worth the upgrade? I have a lot of trailers and football highlights on my pc and would like this to be viewed using the best quality available... Thanks!
