About time you updated to OSX. Yes it will use a bit more ram & perhaps be a bit lower. But it will have the most up to date apps & plug-ins. Also no crashing or freezing of the mac. OSX is supreme in managing ram in that it isolates any problems & blocks them out. So if an app (or even os9 classic) crashes, you can simply re-launch it without any need to restart the comp voluntarily or involuntarily.

Go to QT's Prefs & select plug-ins>MIME settings & tick all options. You could also try pple Video Player http://www.versiontracker.com/dyn/moreinfo/macos/437 (OS7-9)

You could also try allocating more ram to QT.
