I have some classic TV shows on Dvd that, of course were filmed in 4:3 vs todays widescreen/16:9. I am using both a Denon AVR(2809) and a Denon BD player(BD1800). How do I stop the 4:3 shows from getting "stretched" to fit my Samsung widescreen? I've looked through the owners manual of the AVR and BD player and couldn't find anything....emails to Denon get me their standard response, which is to ignore me. Anyone?

Half of communication is listening. You can't listen with your mouth.
