Yes. Your current 60Hz modeline looks something like this:
ModeLine "1920x1080-mine" 148.352 1920 1960 2016 2200
1080 1082 1088 1125
(It's actually 59.94Hz.)
A 30Hz (or, in my case, 29.97Hz) modeline looks like this:
ModeLine "1920x1080-minei" 74.176 1920 1960 2016 2200
1080 1082 1088 1125 interlace

Stick with DVI. *Not* because DVI video is necessarily superior to
component (it isn't) but because most TVs will not apply overscan--a
bad thing when one wants true 1:1 pixel matching--on DVI video but
will for component.

Most TVs' deinterlacers are going to be inferior to MythTV's own
methods; see
