I'm having static and a black/white image on all channels in Mythtv.

Here's the odd piece, it used to work perfectly, have several good recordings. I started working on installing transcode so that MythDVD would work. 

couple of days later I checked the recordings (from TV) I had made and realized that all I had captured was snow. 

checked the mythfrontend log and noticed an error saying that /dev/dsp was being used by another process.

So in the mythfrontend config section I switched it to /dev/adsp, which caused more error messages. Switched it back to /dev/dsp and now I get channels, b/w only with lots of static.

tested with ivtv-tune and cat /dev/video0 > test.mpg.

Signal's perfect there.

here's my mythfrontend log:
