[mythtv-users] pcHDTV and HDTV & CUSTOM RESOLUTIONS

In my Linux-HTPC, I have a list of all modelines for HDTV and other
video formats.  To create your own custom I recommend "videogen".
Google for it and you'll find it.  powerstrip also creates X modelines,
but I have provided 99% of any that people may want.
