Uncross those fingers and get typing again ;)
This basically breaks my 150 completely. Upon startup I have only
static now. I've tried to manually tune the channel with no luck.
I've also tried different input sources, I can get S-Video to work
but anything else fails and there is no audio on the S-Video input
I'm getting my input either via the Tuner or S-Video from a DirecTV
satellite.
I've tried various settings of -p N and -q N to get the settings to work
no, go.
Not sure what info to give you, so to start I've got the ivtvctl -a below
