Actually, Myth's BOB was awesome with my old interlaced TV.  Combine
it with a 540p60 modeline, and the net result was the TV thinking it
was being fed 1080i.  Result was the TV doing the deinterlacing --
which at the time it could do much better than any method Myth had.

This got around the problem with nVidia's drivers not being to produce
a correct interlaced output.
