I have just purchased a Pioneer DVR-720H-S DVD recorder and connected it to my Pioneer PDP-434HDE via a component in on Input 1. Input 2 has my digital cable box input and Input 3 is my HDMi connection from my DVD player. I have had to use Input 1 for the DVD recorder since this is the only input with component for the plasma. I am now unable to change any of the picture settings or sound settings on input 2 for the cable tv. Can anyone suggest what I'm doing wrong? cheers. BTW - the Pioneer recorder is excellent just a pity it doesn't have HDMI.
