[mythtv-users] Guides to calculating HorizSync and VertRefresh for xorg.conf?

Just to make sure (and maybe you're right, the file is wrong somehow),
I've included my "xorg.conf" file in its entirety below.

But first, here's some output from the Xorg.0.log file which confirms
(at least I think it does) that I've got ServerLayout pointing to the
TV:

(==) Log file: "/var/log/Xorg.0.log", Time: Fri May 11 13:00:25 2007
(==) Using config file: "/etc/X11/xorg.conf"
(==) ServerLayout "simple tv configuration"
(**) |-->Screen "TV" (0)
(**) |   |-->Monitor "Sharp27F631"
(**) |   |-->Device "Videocard0"
(**) |-->Input Device "Keyboard0"
(==) |-->Input Device "<default pointer>"

And here, towards the end of that file, I'm seeing these kinds of messages:

(II) ATI(0): Not using default mode "640x350" (vrefresh out of range)
(II) ATI(0): Not using default mode "320x175" (vrefresh out of range)
(II) ATI(0): Not using default mode "640x400" (vrefresh out of range)
(II) ATI(0): Not using default mode "320x200" (vrefresh out of range)

(II) ATI(0): Not using default mode "640x480" (vrefresh out of range)
(II) ATI(0): Not using default mode "320x240" (vrefresh out of range)
(II) ATI(0): Not using default mode "640x480" (vrefresh out of range)
(II) ATI(0): Not using default mode "320x240" (vrefresh out of range)
(II) ATI(0): Not using default mode "640x480" (vrefresh out of range)
(II) ATI(0): Not using default mode "320x240" (vrefresh out of range)
(II) ATI(0): Not using default mode "800x600" (vrefresh out of range)
(II) ATI(0): Not using default mode "400x300" (vrefresh out of range)


Here's the xorg.conf I'm currently using; the horizontal and vertical
ranges came from this site:
