This is somewhat to be expected and not going to be addressed in the near term. It might be that something is not optimal with the OpenGL-based playout on the ATI video chip. Mine uses NVIDIA, and the smoothness is roughly the same as what I get on Linux, which is not as smooth as any of the popular media players. Ultrasmooth playback using SDL has not yet been given a high priority, and the OS X playback is based in large part on that SDL code. Can you give a rough estimate of the roughness? For example, does it look like it plays most frames, but just not timed well. Or, does it look like it only plays roughly 2/3 or 1/2 or whatever of the full framerate? Oh, and I hope you know the framerate is determined by the Project Settings. For example, playing a 29.97 fps video on a 50i or 25p project setting is obviously not going to look smooth. At least you did not reproduce the problem that Marco Gittler reported, and that is the feedback I was really interested in getting at this time.
