Can someone tell me if I've bought the right receiver? I have a Samsung HD-941 DVD player connected to a Panasonic TH-50PX25 Plasma monitor via HDMI cable. I connected audio out from the dvd player to my old receiver with an optical cable. The audio from the 6 surround speakers did not sync up with the video. I learned that the video signal processing was causing the video delay and bought a Harman Kardon AVR 235 receiver that touted the ability to delay the audio to match the video. I've programmed the receiver to delay the audio by approximately 50ms and it seems to do the trick (again routing an optical cable from the dvd player to the receiver). The receiver will do a maximum of 80ms in the audio delay. Can anyone tell me if this 80ms maximum will be enough? I mean, is it conceivable a dvd might require an adjustment more than 80ms? I have thirty days to return the receiver if I'm not satisfied. Thanks in advance for any advice or guidance. Robert.
