OK, I found the user manual for my TV online, and it says the following 
for DTV (I'm assuming that I don't need to worry about the VGA, XGA, 
SVGA, or VESA values given):

Mode      Resolution      Horizontal Freq.   Vertical Freq.   Pixel 
Clock      Sync Polarity
DTV        1920x1080i   33.75                   60                    
74.25                     X
                1280x720p    45.00                   60                  
  74.25                     X
                720x483p      31.47                   
60                     27                         X

How do I go about transferring this to a Modeline value in my 
xorg.conf?  I did find the following link in the Wiki 
(http://www.mythtv.org/wiki/index.php/Modeline_Database) but my TV isn't 
listed.  Should I just mimic the modeline values, substituting the 
values for my TV above?

Sorry if this seems like a dumb question.  I'm still fairly new to how 
the modelines, etc. in xorg.conf work.

Thanks for the help,
Harry
