Can someone help me out. I have had my set up for about one year now and I have constantly had problems on regular Dolby Digital 5.1 dvds. I have a Yamaha 3650 reciever and the sound cuts out ( gets loud then soft) on those sound type movies. DTS sounds awesome but Dolby doesn't. Can someone please help me.
Verify your set up on both the DVD player and receiver. Yamahas are notorius in the complexity of setup. Make certain that you don't have to manually select Dolby Digital on the receiver. Try switching DVD player to PCM. See what happens. Use a DVD that contains only a Dolby Digital soundtrack while trouble shooting.
I have a 4 year warranty on it, so it is not a problem. It happens to my other friends with different recievers also. Could it be the DVD or does Dolby Digital have alot weaker signal than DTS? I have also noticed that it cuts in and out in the same places of the movie everytime. Somebody also told me that I need a power regulator for my whole system. Meaning that my power in my house is not clean power and the regulator cleans it for me and gives me better juice. I don't know.
If it "cuts in and out in the same places of the movie everytime" sounds like a defective DVD. There maybe a slight variation in volume between Dolby Digital and DTS, depending on the movie sound track mix. You should not need a power regulator under normal conditions if you live in the continental US. There may be exceptions.
