Yesterday I tried 384 and it is indeed very good that way - no
stuttering at all on Sat1, Pro7 and ZDF :)
As the switch time goes up I will try to find the best Vaule for this
and I hope to get some help at vdrportal.de for this. I will post
something in the News thread ...

I will try 320 tonight.
