Quicktime freezes randomly for about ten seconds, then resumes playback
Let me explain a little bit the background of my issue. I recently bought a new MBP (mid-2009, 15", double graphics card) and transferred my old system (white MB, late 2007) using the migration assistant. So, might this be a configuration problem, I don't know.
Well, the issue is as follows: randomly, Quicktime freezes for about ten seconds while playing a video. Any video, but usually long movies or tv shows. In fact, the whole system completely freezes (the Dock and other apps, too), I get the beach ball, and about these ten seconds everything gets back to normal. Quicktime resumes playing the movie at a point ten seconds further from the freezing point (as if it were actually playing the movie internally) and the systems gets back to normal.
These are totally random. Not at the start or end of a movie, not when I do anything, not at a fixed time. It just happens, sometimes it doesn't, sometimes twice when playing the same movie. The CPU usage is normal (not 100% as I would expect) but the system is unresponsive.
A last clue: after transferring the old system into the new laptop, Quicktime does not automatically play movies when they are opened, even though the checkbox for that preference is active. If it is a preferences problem, I don't understand why, because they have the same Leopard version, up to date with the latest upgrades.
Anyway, any help would be greatly appreciated. Thanks!
