I recently converted from G4 to G5, and my QuickTime Player is version is 6.5.1. I use OS X 10.3.5. All those movies I saved are now shown plain white documents w/out QT logo like they used to at G4. For ex., I downloaded Enzo1.wmv from other thread, and it won't play. Matter of fact, 5 movies I tried to download here cannot be played. I must be doing something wrong. I searched QT site, and Apple site, but couldn't find appropriate help there. Could someone advise me what to do?
