Hi guys Purchased a new 50" LG plasma tv last week. Set it all up and all was well and good. Looks fab! However, i'm running it through my Yamaha RX-V667 amp and having some really annoying audio sync problems where the audio is lagging behind the video. The amp does have a lipsync option which i have changed and got it to the point where it is a lot better but is still noticible. I am quite a newbie when it comes to AV stuff and was wondering if there is anything else i can change/need to change or whether i am going to be stuck with this problem. If i'm stuck with it then the tv will have to go back because it is an issue that really bugs me. I didn't have this problem with my 42" Panny. Like i say, the problem is a lot better than when i first rigged everything up but it is still noticible. HDMI cable runs from Sky HD box to amp with another HDMI cable from PS3 to amp. Amp then carries everything to TV with another HDMI. Any ideas or solutions? Sorry if i have posted this in the wrong place. Hopefully i haven't.
