Can dvi theoretically output 120 Hz at full 1920x1080 resolution? Or is
it limited to 60 Hz?
I think you could do that on dual link DVI, but I don't remember the math:

If you find a TV that can do that, I would like to hear about it.
Hmm. I've never seen a type b HDMI connector (I don't think). So I'm
guessing you're limited so single-link DVI.

If I'm converting DVI to HDMI signal, can I still play video through
mythtv or mplayer at full HD resolution (1080p) without HDCP or will the
TV refuse to do it?
I believe your assumptions below are correct and the TV generally
shouldn't refuse. I have a Mitsubishi TV plugged into my MythTV over
DVI and X runs at 1920x1080 60Hz without complaint. I've had another
computer with a DVI->HDMI cable and I ran it at lower resoultion
(720p-ish), but it wasn't a problem either.
My understanding of HDCP is that it's the video source that determines
whether or not it wants to display video in HD 1080p mode without HDCP.
In other words the computer or video player (Vista or OS X sadly) that
demands an HDCP "secured" connection. Is this correct? If so then I
think I'll be fine driving HDTV with myth.
Am I okay then?
I'm ok. I think you are ;-)
