I seem to have the very same problem. I am running Knoppmyth R5.5.
My Hardware is a PCChips Mobo with an AMD Geode NX1750 CPU and 768 MBytes of RAM.
The graphics card is an Nvidia FX5200 and the TV card is a Skystar 2.
Connected is a Switch with two LNBs (Astra 19° and Astra 28°). Everything else works fine, i.e. TV reception is no problem with both sats.
I also tried to play radio via mplayer (e.g. mplayer
dvb://"BBC R2") and this also works without troubles. So I think it is not a problem with HW, signal strength or drivers.
But in mythtv I get a black screen and a partial lock message (with LmS). I believe this is a mythbackend problem, because in the mythbackend.log I get these weird errors:

It would seem that the backend somehow interprets the data as video stream.
Can anyone steer me towards how to narrow the problem down any further?
