Playback freezes

Hi! Everytime I want to play a rendered timeline, the playback freezes after a while (just the video, not the audio)  . It does not freeze when playing the unrendered media in 1/4 resolution(R3D). I had a similar problem using CS5.5, which was solved by unchecking the “Save Media Cache Files next to originals”-Checkbox. But this time it seems to be a different problem. Any hints?
