Interesting. I will give that a try.  What about aspect ratio, though?

My TV is natively 4:3, but when fed a 1920x1080i signal it goes into a
"vertical squeeze" mode resulting in a 16:9 aspect.

I have mplayer's default config set up to think the monitor is 16:9, but
feed it the "-monitoraspect 4:3" switch when playing 4:3 material.
