I'm no computer expert but I usually am able to set up my software or system to function and usually dont have any problems. Ever since I have intalled Tiger, half the things don't work. When I installed I did a clean installation as my hard drive had to be replaced. Anyway I cant get any quicktime movies to play. Any real player, WMV or anything else for that matter. Its not the end of the world as all my actual "work" software performs great. Its just frustrating that whenever I get an email with a clip or want to check out a trailer it never works. I installed Quicktime right off the apple website and it wont even play trailers off the quicktime site?!? I researched this and was given a couple things to try but to no avail. Just wondered if anyone else was experiencing the same thing.
