Hello...

you did not mentioned the TV's brand but consider this!

Those any button brings you back to tuner? - like 4 examp. "Ch+" if so !

your action selection on the pronto would look like this...

TV Ch+
TV AV
DVD Play....

unless .... your TV is one of those that you have to go all the way to the end of the tuner to go into AV ... In this case you find the last channel and the scrip will look like this

TV Ch#
TV Ch#
TV Enter
TV Ch+

hope it helps....
