[mythtv-users] MythGame XMame XV Scaling problem [Solved]

[Chris Griffiths]

For anyone interested I took a look at the driver source, it seems 
there's an undocumented option "NoStretch" - which controls whether the 
display will be stretched to fit the LCD screen.

When switching to TV-Out it was still stretching the screen, even though it was no longer on the LCD.

Another one that's useful is "overrideValidateMode" - which stops X from failing when started on the external display - where it can't probe to find the acceptable modelines.

It's cool getting to play Wonderboy again :)
