First ever post having lurked here for almost a year, so be gentle please! Thanks to all the great advice on this forum I got myself a Denon 3802 to partner a Panasonic series 4 plasma. Great sound but......Lip sync was rarely mentioned 4 months ago - it seems all the rage now. After 4 months of frustration with sound and vision out of sync I bit the bullet, sold the 3802 and bought a 3803. Brilliant, sound and vision perfectly synchronised from one DVD. Switched to another DVD - readjustment of the audion delay needed. Switched to Sky, audio delay needed another tweak. Got that spot on, changed channels and hey presto audio is out of sync again. Am I just fussy or is it a case of having to set up the audio delay every time you change channel or change sources????
