Have you tried checking that ivtv is loading properly? Place the
following line in your config:
options ivtv ivtv_debug=2
If you already have options for ivtv declared, just add the
"ivtv_debug" on the end
Remove all of your ivtv-related modules (ivtv, tuner, tveeprom, etc.),
or alternatively you can just reboot your machine. Then load ivtv.
Run dmesg (or check your /var/log/messages" and post the output
between the "**** IVTV *****" lines.
You can run "dmesg | tail -f" to watch the log while you fire up ptune-ui.
Be careful if you decide to actually capture some video while changing
channels. I wouldn't try looking at the ivtv debug while you're
capturing. You'll get a billion messages about DMA blocks being
transferred. Use ivtv_debug=1if you want to get rid of those
