Thank you for the quick reply, I haven't been online in a while.

Yes, I do and always had a good signal. I do suppose that Version 6.60.02 would show the same symptoms, if I had a bad signal.

But I tried your suggestion and changed the Demultiplexer from "Microsoft" to "Prog" and that seems to be ...

At all versions after 6.60.02 the picture and sound freeze most of the times, when the progress bar at the bottom of the video screen reaches the right side.
When changing programs, all is ok again, until the bar reaches the right side again.

Version 6.60.02 works very well.
