It looks like that new QuickTime 7.4 broke a lot of things..Among others you cannot load subtitle files with Perian any more and I think QT 7.4 now loads DivX using some other thing and not the Perian, but Im not sure...Also this update broke the ability to load MPEG2 video track together with .wav or .aif audio - e.g. when you click on .m2v /MPEG2 Video track/ and if you have the .wav audio with the same name in same folder as video, QT 7.4 wont open audio, only video...

Is it only me or others have similar issues?
