I have found some scripts and might add it on the weekend and then publish the viasat site again afterwards. I'll need testers though, so you're invited
Did you try more than one category? Do TV3 or TV6, TV8 play?
Please create Logs with MediaPortal Log verbosity set to Debug and attach them here. TV4 is region blocked so I can't really try from here.
From the logfile, it looks like the connection is always working on tv4, but you abort it, before playback starts. Can you please use Blue3Wide for a test -> it show the buffered % before playback. It might just be a little slower to get the data.
I tried it again now, and while most times the buffering just stops, I actually got one of the clips to play, typically my Wifi died right before so I don't have a clean log, but I'll try to get that for you if it helps.
