That's good to know.  But you understand that blank screen and a logfile
that says 0Hz sounds related?  :)
I went through the steps on the wiki and verified that my tv can handle all
the resolutions in my xorg.conf so I'm not sure why I would get a blank
screen.  Any ideas?

That has the side effect of killing my sound over hdmi.  That's a big
problem for me so I reverted back to "UseEDIDFreqs" since I couldn't find a
work around (and I'm tired).

I left the NoEdidModes in and removed the interlaced mode.  Quick test shows
I still have a big audio lag after switching to 24Hz but I haven't done
enough testing yet to see if the blank screen returns.  When I tested with
xrandr 24Hz displayed fine on my tv.  Do you still think I should remove
24Hz (and/or 23.976Hz) from my xorg.conf?

My tv tells me the difference between 1080i and 1080p but don't think that's
relevant to whether the modelines look different to mythtv.  Regardless I
removed the 1080i mode.

Thanks for all your help!
