But in my case, the frameskipping problem, that occurs since around the last 4 Testbuilds, isn´t fixed. Nearly every Movie I have is skipping every 15-20 sec.

I don't know about the frameskipping problem. Has this been reported before?
You'll have to describe exactly what you are seeing, and what the last build is that doesn't have this problem.

Its difficult to describe. Most of my videofiles I play are stuttering for less then a second every 10-20 seconds. I stream all from my harddrive attached to my airport extreme connected over ethernet to the raspberry. The network should'nt be the problem.
