I've some problems with watching non FTA channels. In TV server configuration everything works fine and if I do preview everything works. Then I start MediaPortal and select an non FTA channel, then I get the following message: "LIVE4-0.TS.TSBUFFER". What does this meassage mean and how can I solve it?
The strange part of it, is that when I first start with watching a FTA channel and then go to an non FTA, everything works fine.
Hopefully some can help me with solving this problem.
