[mythtv-users] xorg.conf example for TV

[awrobinson at nc.rr.com]

Since I asked, I thought I should post the answer. Here is the xorg.conf
file that allowed me to see MythTV on my TV. The video card is an nVidia
5200 with a VGA and an S-Video connector. The TV is the main screen on
the right. The monitor is a secondary screen on the left. There was some
trial and error involved as the X server would fail, I'd look through
the log to see if it gave me a clue as to why, I would remove or comment
out what appeared to be the offending feature, then try to start X
server again. 

There are still two, uh, issues I could use help with. 

1. The active area on the TV is not square. It looks like a
parallelogram, with the left-hand corners lower than the corresponding
right-hand corners. At first I thought it might be a sign of interlacing
problems, but the picture is otherwise clean with no flickering. This is
a very old TV and I am running the signal through an S-Video to RF
converter, so I cannot swear the problem is with the Linux box. Anyone
have any ideas of what might cause this?

2. The active area on the TV is a letterbox, with considerable blank
area at the top and bottom of the screen. I assume this is a result of
the resolution of the display, which I think is 800x600 at the moment.
Anyone know a resolution better suited to an old 19 inch analog TV?

Thanks!

# To customise the XKB settings to suit your keyboard, modify the #

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#     Option "XkbLayout" "de"
# or:
#     Option "XkbLayout" "de"
#     Option "XkbVariant" "nodeadkeys"
# If you'd like to switch the positions of your capslock and # control

#     Option "XkbOptions" "ctrl:swapcaps"
