~- Some movie formats don't like seeking during playback, playing at a different rate than the normal speed or playing them backwards. Other movie formats are perfectly fine with that. In our experience, the H.264 video format proved pretty robust and reliable, efficient as well.

~- Quicktime has problems with playback of multiplexed MPEG-1 and MPEG-2 movies, which can cause instability and random failures. Apple provides a free tool to convert such MPEG movies into a format that Quicktime can handle well.

=== [[http://psychtoolbox.org/wikka.php?wakka=PsychtoolboxFaq FAQ]] - How to resolve ""QuickTime"" problems: ===
**A:** Some people sometimes experience instability when trying to play back some types of Quicktime movies. This is mostly due to some bad interactions between Apple's Quicktime engine and Matlabs built-in Java virtual machine. It only happens with some movie formats (Codecs), not with all of them. The following has helped in the past:
~- Run PTB under OS/X 10.4.x "Tiger", not on 10.3.x. Tiger seems to be more stable.
~- Use the most recent version of Quicktime.
~- If the problem persists, run Matlab from a terminal window in -nojvm mode, i.e., without the graphical user interface and Java. Start it with //matlab -nojvm//. Running without Java resolves about 95% of all crashes.
~- Some movie formats don't like seeking during playback, playing at a different rate than the normal speed or playing them backwards. Other movie formats are perfectly fine with that.
