[vdr] pvrinput radio

I've asked this before, last year, but never had a response.

How do I configure radio channels in VDR.

My channels.conf has:

Classic Hits:90000:I999C0:C:0:0:300:305:A1:12003:1:1006:0

But I think I'm picking up the wrong device, as I hear no audio. I have a single PVR-150 with ivtv and the following devices:

/dev/video0 /dev/video24 /dev/video32

When I do a 'ivtv-radio -f90000' I see: aplay -f dat < /dev/video24 #which works

So....what should my Parameters be??

C0 - Input 0 C12 - Input 1 C23 - Input 2 C34 - Input 3 C45 - Input 4 C56 - Input 5 C67 - Input 6 C78 - Input 7 C89 - Input 8 C999 - Input 9

Thanks - in advance!
