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

[Andy Grundman]

I originally had my PVR-250 working fine and recording very good quality 
video.  Then for no apparent reason the video now looks very fuzzy and 
has vertical green bands.  Here is a screenshot:

I saw a post about incorrect tuner settings causing vertical bands but 
nothing has changed since it was working.  My module config is exactly 
the same as Jarod's.  I am using the latest ivtv 0.1.9.
