I have a JVC-778VBK receiver which I know isn't top of the line by any means but has been OK for me until I upgrade, my problem is that when I was playing back the Shrek DVD my wife noticed a couple bits of audio missing that were in the movie seemingly songs only, I played it on my bedroom system and they are there using this other DVD player and receiver. This tells me I have a problem somewhere. Then I bought the Journey 2001 concert DVD and when trying to playback in 5.1 DD there is very little if no audio coming from my front speakers, it is all coming from my rear surrounds, but when I set the DVD to play it back in stereo it is OK albeit only in 2 channel stereo, I tried my other DVD player with this setup and have gone over all the settings (I think) on the receiver, still no fix. My question is, is there something wrong with my receiver or do you have any suggestions as to the problem? My DVD player is hooked to the receiver through the optical audio cable.
