Update:

I got 1020x768 and 1280x1024 working at 60Hz. 1280 was too high, but 
1020 looks good.

I failed to get resolutions like 720p to work (which I would like to at 
least try as I have a 16/9 projector), but 1020x768 looks good and I've 
set up a DisplaySize line so that Myth is set up correctly.

I tried (briefly) using
Option "ModeValidation" "AllowNon60HzDFPModes, NoDFPNativeResolutionCheck"
but I couldn't get different frequencies working. I may come back to 
that or I may just settle with what I have. It's taken a LOT of work by 
some very helpful people on this list to get this far and my display 
looks good.

The only other thing I'll probably try is to set up a low resolution 
modeline with double scanning so that mame can be run full screen. I 
assume something like 320x240 is what's needed there, but I'll look into 
that further down the line.

Thanks again for everyones help!!!

Cheers
