Don't even need to de-interlace (one frame* is good enough) as I have an interlaced display.  I gave it a quick try this morning and it didn't seem to switch to Full when watching a recording of Gilligan's Island on an HD channel.  Is there something else I need to set?

I wonder if the issue is that the broadcast really is in HD,
even though only the SD portion of the video frame is used for the program?
In otherwords, the letterboxing is actually part of the recorded program,
so mythtv figures it belongs there (?)

In the rest of the world, an SD show apparently quite often uses only SD for
not here in Canada.
