Great.  Thanks.

I wish there was some way to know.  The TV itself offers 1080i
(actually 1920x540p) and 480p modes via ddc.  But the docs say it
supports 720p also via DVI.

The interesting thing is that my powerbook finds 2 modes. 1920x540p
(which looks awful, and there is no way to get a mac to interlace), 
and 720p.  I wish I knew where it was getting the 720p mode from.

My 1080i mode is a simple conversion of the 1920x540p mode, and my
720p modline is one of the various online modelines that are floating
around.  At least to me, it looks a lot better when getting 1080i
input via DVI than it does with my 720p modeline.  But that could be
because I futzed that modeline, or I'm just not doing the correct
kind of deinterlacing.
