I connected my Pocketdish AV500e to the front panel inputs on my 721 and changed the 721 channel to channel 0.  When I switch the Pocketdish from LCD display to TV display, what is displayed on my Panasonic plasma is horrible - messed up colors and horizontal lines. 
What might I be doing wrong?
thanks.
