Uncompressed QT, or AVI, are virtually impossible to play unless you have a nasa supercomputer. They are intermediate renders, designed to prevent you losing quality when you do further work on them. If you're rendering a final file to view, you probably don't want it to be massive anyway: try divx or mpeg. Or QT photo jpeg at 90% looks as uncompressed as it gets, but should be playable.
If youre doing further work on your render and have the drive space, lossless codecs are the way forward.
