i have asked a lot people about a particular problem i have with my lg dvdplayer/vhs recorder ..when i play a vhs sound starts immediatley ..when i start a dvd sound takes 4 mins before it starts ..it is plugged into a digital amp with no issues ...seems to happen more on dvds ive burnt than on originals but does happen on them as well ...the picture starts with no sound then 4 mins later the sound just starts...any ideas??
