I had the same problem and was by codecs.Hi. I have scanned and found all channels from my IPTV provider, and I'm able to watch them in the TV-Server preview.
I have also mapped all channels but none of them shows up in MP when trying to watch tv.
any ideas what is going wrong here?
I solved it with the following codecs (I use Elecard filters):
* MPEG-2 Video decoder: Elecard MPEG-2 Video Decoder HD.
* H.264 Video decoder: CoreAVC Video Decoder.
* MPEG / AC3 audio decoder: AC3Filter.
The versions I used are:
* Elecard: "Elecard MPEG-2 Decoder & Streaming Plug-in for WMP 3.7.90209"
* CoreAVC: "CoreAVC Professional Edition 1.9.5"
* AC3: "AC3Filter v1.51a"
Unfortunately Elecard and CoreAVC are not free.
