You don't say what distro or TV type you are using, but usually this can 
be controlled by locking your vertical refesh to 60hz (NTSC) or 50Hz 
(PAL).  Look in your x config file (/etc/X11/XF86Config for me on 
Knoppix) and find your "VertRefresh" line. Edit it to read "60 - 60" (or 
"50 - 50") as apropriate.
