wyllisx1, first...congratulations on the new gear!
I downloaded the owners manual and started to check it out, but then I realized that I should have asked some questions:
1) Which audio out jack(s) are you using with the v659?
2) Which audio out jack(s) where you using on your v430?
3) You're only getting mono from the TV and nothing from the DVD player. Is this true only for the headphones, or is it also happening with the main speakers?
Also, just curious, which headphones are you plugging into the receiver?
