well im one of those people thats having trouble with quicktime player 7.3. some times i just get the bar across the bottom but no picture. i have a powermac g4 with osx 10.4.11. i have read a lot of posts about what to try to do to correct this problem but no help. any suggestions. it would be nice to choose what player to run some of the downloaded movies instead of it going automatically to quicktime. from what i understand this is a pretty common problem. i tried to uninstall quicktime 7.3 but can't figure out how.
