I have the HL-R6167W.  I tried forever to to find a good modeline, but never did.
I was also using the DVI jack.  Picture was pretty good using this modeline:

Modeline "1280x720" 74.500 1280 1344 1472 1664 720 723 728 748 -hsync +vsync

but there was a slight moire effect and I didn't like the overscan, there was too
much.  Finally I learned that I didn't need a modeline and Xorg would determine 
the settings on its own using the PC Input. Now, the picture is perfect, with only
a slight overscan, maybe 5-15 pixels in each direction.  When watching TV,  a little
overscan is _good_, since most broadcasts have a crappy edge because overscan
is expected on regular TV's. Just have the MythFrontend GUI in a window, adjust
to match your screen area, and play video back full screen. Works perfect for me.
