Boot and press R1
Wait 4 seconds, release R1
press 3 times down then B button (boot in CLI mode)
wait 10 seconds
type username, enter, password, enter
run something like
sudo -n /usr/pandora/scripts/op_tvout.sh -t pal -l 0
(I do not have a cable yet, so basically, I am guessing here)
Then, now that you have a visual, edit a /etc/rc5.d/autostarttv file of some sort, a linked file on your sd card.
Good luck!
edit idea for new OS release:
Press L1 while booting, will autostart a program that allows you to switch tv on or use last-known.
Cant we autostart a pnd at boot? (specific name, could give audio queues)
