You'll need to specify a modeline compatible with your TV.  Check the
mailing list archives - I went through this with my Samsung DLP about 6
to 8 weeks ago (or thereabout).  My mythtv box is currently suffering
from a failed BIOS upgrade so I can't currently get at my xorg.conf
otherwise I'd tell you exactly what I have.
