This particular problem where a MythTV box will not connect again
after a TV has been off (or in standby or unplugged) is usually able
to be fixed by copying its EDID data and getting the Nvidia drivers to
load the copied EDID data instead of trying (unsuccessfully) to get it
from the TV.  Presuming, of course, that you are using an Nvidia card.
It may also work the same way with other drivers, as it seems to be a
problem at the TV end that causes it.

Here is how to copy the EDID data for Nvidia drivers:

When using that page, make sure to start the Nvidia tools mentioned
from a root prompt or with sudo, so that they have permission to write
to the /etc/X11/xorg.conf file.
