I'm having trouble getting one channel to come in cleanly over my PVR-350 (using ivtv-tune -c# && cat /dev/video0 > test.mpg)
It's usually channel 5, sometimes 63 (us-cable). The other channels are
usually nice and crisp.
When the channel is bad, it comes in all wavy/flickery. A sample should be up
on Google Video:
http://tinyurl.com/6mfnty (may or may not be working...)
(Longer URL: http://video.google.com/videoplay?docid=-7533649095502027426 )
Screen capture attached showing the waviness.
Specs and stuff below.
I'm using motherboard video for output, not the PVR-350's output.
I've had the card working in Windows for years, but just moved everything over
to Ubuntu. The card is not too hot.
If I switch the cable to go directly to the TV, the suspect channel comes in
fine (on the TV).
Thoughts?
Thanks,
Jonathan
