[mythtv-users] Ahh - Evil xorg and modelines

Back to basics. I'm currently switching between my old backup xorg 
(which had 800x600 working fine) and the modified one that I'm working 
on to keep the misses happy when she wants TV.

I'm now humbly just trying to get 800x600 at 60Hz working as I know that 
works fine when edid is enabled.

I've tried setting the mode to "800x600" with no modeline, but that 
didn't work.

I went to http://xtiming.sourceforge.net/cgi-bin/xtiming.pl and tried to 
produce a mode line based on this info from my BenQ W100 manual:

Supported timing for PC input
            Horizontal Vertical   Pixel
Resolution  Frequency  Frequency  Frequency  Mode
            (kHz)      (Hz)       (MHz)
800 x 600   37.879     60.317     40.000     SVGA_60

The mode line it returned was:

|Modeline "800x600 at 60"       38.44   800  832  976 1008    600  612  618  631

this didn't work.
I remembered someone saying that the first number should be the same as Pixel Frequency, so tried editing to

||Modeline "800x600 at 60"       40.00   800  832  976 1008    600  612  618  631

That hasn't worked.

I just don't know what to do with this. I keep expecting a breakthrough, but nothing's coming.

Any ideas?
