[mythtv-users] Filling TV-Out screen?

Hello,
I've finally gotten my MythTv Box working, as far as I can tell, though
the mythbackend does randomly die sometimes. I haven't fully debugged
that. One thing I can say is that disabling acpi (with the kernel
parameter acpi=off) was a big help.
Anyway, I have a Shuttle SK41G with a ProSavage card and a WinTV-D. The
video output quality from this setup is so far leaving something to be
desired. My big issue right now is that the displayed video does not
use up the full screen on the TV. I'm currently running in 800x600
mode, and letting the video card scale appropriately on the TV-out
port. I've connected the s-video tv-out port on the PC to an RCA jack
on the TV (using a conversion cable that came with the PC's video
card).
Is there a better way to setup X11 so that the output will be the
correct mode for the TV to start with? Something resolution that better
matches the NTSC signal? Right now the vertical is filled in fairly
well, but there is a fair amount of black area to the left and right of
the screen.
I found some modelines out on the web, but when I start X, it throws
them away saying 'hsync out of range').
Here is the relevant snippet of my XF86Config file:
Section "Monitor"
Identifier "TV"
# HorizSync 30-50
# VertRefresh 60
HorizSync 30-85
VertRefresh 50-160
ModeLine "720x480i" 13.59 720 727 791 864 480 484 487 525
interlace -hsync -v
sync
ModeLine "800x480i" 15.10 800 808 879 960 240 242 244 263
interlace -hsync -v
sync
EndSection
