Issue with Resolution on TV output

[Lindy Bryanton]

Hi All

I just built a new computer that I'm hoping to use as a media center. I am
having trouble  getting the video to display properly to my tv and have
spent the past 4 days searching through forums and trying different
settings. I am hoping it can be fixed with the right settings in my
xorg.conf file.

When I boot up with my LCD plugged in through VGA, everything is great.
When I boot up with my TV (a 27" Toshiba - nothing fancy) plugged in through
component video, I get a resolution of 640x480 resulting in an inch of black
up the left and right sides of my TV.
If I remove the s-video to component video cable and connect the  box to
the  TV using just S-Video, the video fills the screen, but it is in black
and white.

So here's my current setup:
I have an Asus M2A-VM HDMI motherboard with onboard video (ATI Radeon X1250)
It came with card that has video out, hdmi out, and component video out. The
component out is really an s-video out with a cable that converts it into
RGB.

I am running Ubuntu 7 (64 bit) because I thought it would be nice and
lightweight for the job. I also tried Ubuntu 8 and Fedora 7 with similar
results. I enabled restricted drivers and it is using an ATI accelerated
graphics driver. I also tried manually installing the driver as per
instructions on wiki.cchtml.com.

When I type fglrxinfo, I get:
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon Xpress 1200 Series
OpenGL version string: 2.0.6334 (8.34.8)

Any help would be hugely appreciated.
Thanks,
Lindy
