I basically get NO data (zero bytes) when I cat /dev/video0. I'm sure it's something I've misconfigured, but I groped through all the dmesg (see below) that I could find and didn't get any clues (on either 2.6.17 or 2.6.15).
Based on the troubleshooting, i tried changing inputs and channels. When I change channels I can prove that the tuner is correctly detecting input because I get this with the cable TV plugged in:
[EMAIL PROTECTED]:~$ ivtv-tune -c 2
/dev/video0: 55.250 MHz (Signal Detected)
If I unplug the cable, the signal detection goes away, so it seems that the inputs are ok.
Any ideas on where to look next? I would greatly appreciate any leads, I've been fighting with this for days.
thanks
