John,

The part I'm concerned about is the part where you say, "I have a 
720x576 modeline on a PAL 16:9 TV. By default myth treats this as a 4:3 
display."  So, I'd just like to verify your system configuration, which 
will make it much easier to duplicate the issue.  Can you please post 
the output (~/settings.txt) of:

xdpyinfo 2>&1 | tee ~/settings.txt &&
cat<< "EOF" | mysql -umythtv -p mythconverg 2>&1 | tee -a ~/settings.txt
SELECT * FROM settings WHERE value IN ('AspectOverride', 'Zoom', 
'GuiWidth', 'GuiHeight', 'GuiSizeForTV', 'UseVideoModes', 
'GuiVidModeResolution', 'XineramaScreen', 'XineramaMonitorAspectRatio');
SELECT * FROM settings WHERE value LIKE 'TVVidModeResolution%';
SELECT * FROM settings WHERE value LIKE 'TVVidModeForceAspect%';
SELECT * FROM settings WHERE value LIKE 'VidMode%';
EOF

Thanks,
Mike
