I think that i've further narrowed down the problem. After bringing a
different box downstairs and trying on the same display, I've learned a
few things. -- If myth/myplayer outputs a 1080i signal at particular
resolutions (such as 1680x1050) it will disort the output as described
below.
-- If other output resolutions are used it works great. Ie 1400x1050
works fine.
The best way that I have found to play with this is to leave X at a res
of 1680x1050, and use the appearance options in myth to try different
resolutions. I haven't really tried very many, since i discovered this
late last night.
Now I wondering if the problem is with the wide screen (16:10) nature
of the 1680x1050 resolution, or if it is just too high or something.
I'd obviously like to run at 1680x1050 since that's the native
resolution of the LCD, and also i would want it to be wide, since
widescreen is obviously better.
What can i do? Does anyone know why I can't use the correct
resolution? Is there another resolution that would be close that might
work? What can I try?

Deinterlacing is clearly not working in these pictures. The stripes are
so wide because something (probably your video card) is scaling the
pictures to a resolution less than 1080 lines high. Double-check you
have deinterlacing enabled, and check the output from 'mythfrontend
--verbose playback'. Also note that bob deinterlacing is disabled if
you're playing at a speed other than 1x.

Doug is right on. That is classic when resizing non-deinterlaced
content. You can also see this problem if your filter chain is in the
wrong order, and you resize *before* deinterlacing. You should always
de-interlace prior to resizing.

Hmm.. I am using kernel deinterlacing. Or at least thats what I
specify in the menu. I don't have any other exotic filters or
anything. I am playing at a 1x speed (normally) The display is
outputing onto a lcd flat panel at 1680x1050, the native resolution
of the display. I have Xorg setup to do this resolution.
I don't know how I would re-arrange the filter chain. Is this
configurable somewhere? I assume that X is doing the scaling from the
1920x1080 to the 1680x1050. Is this correct? If myth is doing the
de-int, it should be taking place before the scaling right?
