new'ish low profile pvr150

[Mark]

I bought a low-profile pvr150 card, but after loading the cxm and setting the input with pvr250-setchannel, I get a black screen without audio.
It does not have composit input, just an FM-cable, TV-cable S-video and IR. I've tried both inputs but no joy. Any chance to get it added the the cxm driver?? ;)
