Hi all, apart from a few small bug fixes and improvements, the beta branch of Psychtoolbox has been updated with initial Quicktime movie playback support for Microsoft Windows. Quicktime demos can be found in the Quicktimedemos subfolder of the PsychDemos folder. They are the only and therefore best documentation on how to use it. Obviously you need to have Apples Quicktime for Windows installed to use it. This is a beta-quality implementation that may contain some bugs or limitations. It has been successfully tested on two machines, but use with caution and prepare for a bumpy ride. This implementation is also not optimized for performance yet and Apples QT toolkit for Windows seems to be generally less well tuned than the OS-X version, so you'll probably need a recent PC if you want to play big movies without too many skipped frames. A good first test is always to play the movie in Quicktime player. If it plays back flawlessly it may also work well in PTB. If it doesn't, then it will be certainly worse in PTB. good luck, -mario -- \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* Mario Kleiner Max Planck Institute for Biological Cybernetics Spemannstr. 38 72076 Tuebingen Germany e-mail: [mario.kleiner@...](mailto:mario.kleiner@...) office: +49 (0)7071/601-742 fax: +49 (0)7071/601-616 www: [http://www.kyb.tuebingen.mpg.de/~kleinerm](http://www.kyb.tuebingen.mpg.de/~kleinerm) \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* "Debugging is twice as hard as writing the code in the first place.
