Bummer.  I am using the 3.7.10 kernel on Gentoo.

I don't see anywhere in the mythtv-setup to update the CC source and I am
guessing there is no script I can manually change.

If there is no easy fix maybe I will try these HD-PVR scripts.  Where there
any other major changes that would be helpful to know besides the /dev/vbi
VBI setup?
