I would like to get this sorted too.

I've just about got it right but it isn't perfect. I have a Sony 32" 
Widescreen (PAL UK) connected to an nVidia 440MX via S-Video. I tried 
fiddling with the X.org config and I think I have the aspect right but to get 
the overscan working I'm using nvidia-settings. I have expanded the screen so 
that the picture is slightly off the sides but annoyingly just short of the 
top and bottom. If I move the slider any further I get too much side 
overscan. Even as it currently stands the Myth menus can sometimes be off the 
edge.

I tried a modeline generator which made the Myth menus fit better but TV was 
then letterboxed(!) so I gave up on that.

The other final thing is I can't get it to run in 50Hz so it's stuck in PAL-60 
all the time which means a bit more flicker than I would like.

If anyone out there has got a neat way of sorting these issues out for myself 
and Dave above then I'm all ears. Well, eyes actually as this is email!

Thanks
