[mythtv-users] PVR-250: Vertical green bands in recording

[Douglas Beck]

Hey, Andy.  I have this problem when my card switches to 720x480 
spontaneously from 640x480.  I just make sure I'm not watching live tv 
or recording anything and issue this command:

# /usr/lib/ivtv/test_ioctl -f width=640,height=480

If you're running PAL you're going to have a different vertical res.
