An .avi movie would not play in QT 10.2 but plays fine in QT 7.6.6---
I restarted and the same problem-- a movie opens fine the first time with QT 10.2, then I try another and it freezes - have to force quit and it will not play that movie.
This may or may not be normal. Some AVI files (especially those using certain "legacy" codecs) won't play at all. Others QT X may ask if I want played in QT 7. And still others may may play in this "on again-off again fashion. I normally default all AVI content to QT 7 playback to avoid non-plays, mis-plays, and/or switching apps.
Is the movie corrupt?
Probably not. More likely it is a "new-technology" (i.e., QT X recognition/programming) or "security" issue causing problems—i.e., a characteristic that QT 7 does not bother to check for and so ignores since the file is otherwise playable.
As indicated above, why not just play all your AVI files in the QT 7 player or VLC?
Can one re-download QT 10.2 ???
Not as a separate download. You can however, re-download the installer package file and extract a copy of the QT X Player from it. However, I suspect there not be anything wrong with your QT X player app is this is your only so-called "problem."iMac, OS X Mountain Lion, 3.4 GHz Quad Core i7, 4 GB 1333 MHz

First let me say that this is one of the finest (and fastest!) replies I have received and I've been using a Mac since 1989 and on the discussion group since it started! I did suspect a "problem" with the movies in .avi format so converted them to .MP4 -- and they played fine on iTunes and with QT 10.2 after the conversion.
All your information is valuable and I'm saving this post on my HD. I shall divert .avi's to QT7 if I don't convert them.
Thanks very much and I also appreciate your detailed information – going beyond the call of duty here and that really is super!
Best of continued success--
