Hi all,<br><br>I am having a weird problem with my mythtv setup, using a PVR-350 for output. <br>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.<br><br>I have been running myth for about 2 years with this setup, and recently (september) upgraded to ubuntu and Myth 0.20.2.<br><br>Can anyone tell me where to look next to fix this problem? How to collect more information? what to collect?<br><br>Any help would be appreciated.<br>--Gord.<br><br><br>=======> from my .gnomerc <====<br><br>while /bin/true<br>do mythfrontend >> mythfrontend.log
