[mythtv-users] problem with pvr-350 output shifting colors and/or shifting sideways

Hi all,

I am having a weird problem with my mythtv setup, using a PVR-350 for output.  
The problem is that the screen will shift in the display, and lose a color, or quite often changing the screen to bright green and magenta. This happens at random intervals, between 15 minutes and 6 hours.  I discovered that if I unload/reload the saa7127 module, this would reset the screen, and then the dislay is fine again (for the random interval of watching.)  I did do a search of the archives, and did not find anything that looked similar.

I have been running myth for about 2 years with this setup, and recently (september) upgraded to ubuntu and Myth 0.20.2.

Can anyone tell me where to look next to fix this problem?  How to collect more information?  what to collect?

Any help would be appreciated.
