I've played around with the time remapping function of CS5, and have the strange problem that as soon as I change the speed of a clip via time remapping, the preview frames in the timeline view get messed up - they show a totally different part of the clip. I even cant fix this with rendering the whole workspace or reloading the project.

On a side note, changing the speed via speed/duration dialog, the preview frames are shown correct.

Is this a bug or do I miss something?
