Should udev not play the game after reboot, log in as root and run the
commands you had to do to get /dev/dvb/adapter0 to appear the first
time. Check again for the existence of /dev/dvb/adapter0/ and if it is
there copy it like this:

# cp -a /dev/dvb /etc/udev/devices/

To allow user 'mythtv' access to the device files change ownership like this:

# chown mythtv:mythtv /etc/udev/devices/dvb/adapter0/*

This makes udev create the device files on every boot and gives
'mythtv' access to them.
