Mac OS X 10.9.4
Short description of error
Editing a multi-strip project on VSE, I am not able to playback smoothly the sequence.
No matter if I change the value in Blender preferences (System - Seuqnecer/Clip Editor: Prefetch Frames), the playback hangs and even Blender become unresponsive.
By the way, the documentation (http://wiki.blender.org/index.php/Doc:2.6/Manual/Preferences/System) says that there is a limit on "System - Sequencer/Clip Editor" values. If the documentation is updated and this is still applicable, I think the controls of UI should limit the numbers. Should I open another bug for this UI issue?
