Sounds like possibly a heat or a grounding/shielding issue.  Here's how 
to tell if it's the driver or the hardware:

- stop mythbackend
- modprobe -r ivtv
- modprobe ivtv
- start mythbackend

If this clears up the problem without a reboot, then it could be a 
driver issue.  If not, it's more likely a hardware issue.
