[mythtv] 720x480 video corrupted

[Trevor Kramer]

Hello,

I am running svn mythtv on a EPIA board (CN700 North Bridge) using a  
PVR-500 for captures. I am using the latest svn version of the  
openchrome drivers and using regular Xv output. When capturing video  
at 720x480 the video plays back corrupted with red diagonal lines  
across the screen and a green bar at the bottom - I have a picture of  
it here - http://www.trevorkramer.com/myth_corrupted.jpg. The same  
file plays fine in mplayer and xine. When capturing at 480x480 or  
several other settings it plays back fine in mythtv. Anyone have any  
idea on why 720x480 would not work in myth but other resolutions  
would?  Any pointers on where in the code to start looking?  Thanks,

Trevor
