Hi UVDan,

I do use the h.264 QT codec so your QT may simply need to be updated. (It's free - http://www.apple.com/quicktime/)

I do know that VTC compresses the movies to the lowest common denominator for video viewing on the Web for obvious reasons. I don't do that. However, I can fit twice as much content with better clarity within the same Megabytes. Ergo, my choice for h.264.  :-P The Web always bites back somehow.
