[mythtv-users] xorg.conf for 1280x720 HDTV

[Tomi Makinen]

There is a utility (atleast in fedora) called xvidtune. With it you
can try to adjust the screen. For some reason I just cannot get
perfect picture to my panasonic ae700. always some overscan at sides.

Anybody have some good modelines for me.. maybe for 75Hz ?
