[mythtv-users] Help: Disable X & Edit X config

[Travis N]

I am new to linux & myth, but at one point successfully had both
functioning.  In my blind attempts to get the S-video out hooked up to my
TV, I changed my X config file to force S-video out.  This was successful,
but the HorizSync setting seems to be set wrong, as the output image seems
to be smeared across/around the screen horizontally.  Now when I plug my
monitor into the VGA connection, it will no longer output to the monitor and
I cannot see what is on the TV in order to log in and modify the config file
in KDE.
 
I am guessing that I have to prevent X from booting, and edit this file from
outside of KDE somehow, but have no idea of how to do it (s-video works
great until X loads)..  basic step-by-step instructions would be greatly
appreciated! 
 
Also, if someone could direct me to the appropriate config settings
(HorizSync) for a run-of-the-mill 27" RCA TV (NTSC), that would also be
greatly appreciated.
 
Thanks-
 
Travis
