Ubuntu x64 Radeon ATI 1550 TVout is rolling / flickering working xorg.conf


After much, much reading and tinkering i have become very familiar with xorg.conf. Im good at making backups and testing and such. When i started i could not even get the drivers to work with my radeon card.

Anyway long story short, everything is working, but my tv out "rolls". I can see my desktop on the tv but it seems to be rolling downwards. Of course everything is in my xorg.conf but could it be the refresh rate ? Anyone know of a easy way for testing or what my values should be for my tv ?

thanks, here is my xorg.conf

Code:
# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

To be honest, your knowledge of the xorg.conf file would be a lot better than mine, although I do remember, back in high school, being told by my electronics teacher (who ran a mobile pc repair business part time) saying that TVs always come out with a bad picture because they can't run at a high enough frequency, so maybe if you tried setting it to run at a really ridiculously low frequency, if thats even possible, but thats the only suggestion I can give, good luck
