If you want to watch the quicktime videos in full screen on your pc, just use QuickTime Alternative - imo much better than regular quicktime!!
😄
The only thing about this compared with QT Pro is that I don't think it can do any editing with the QuickTime video... it's a player only. It works fine on webpages or files on your hard drive. It uses Media Player Classic to view them - which is actually a better player than Windows Media Player in alot of ways. 😎
