The permission problem is in the access to the /dev/dvb tree. Of course
root can access that, but user mythtv cannot. You can test it by doing
a chown and chmod but that will not last past a reboot.
The place to make a permanent fix is in udev.
If you look in the /etc/udev/rules.d folder you will see some xx-rules
files. You need to change the group ownership and mode settings for your
hardware device socket...You may, or may not have a rules file for the
HD3000, but the format is plain enough from the 50-rules file.
Check the archive for the exact wording if you have a problem... or
maybe Jarod covered that already.
