Hi,
Yes, tis unit has 2 video inputs at rear so you can connect any other dvd player sound (analog or digital) to get 5.1 channel surround sound from DAV-C770 speakers.
Click Sony Support to download user manual copy of DAV-C770 that has more details about connection setup.
Hope this info will help you.
Thanks.

The dvd mech is out of aligment.This is a common problem with this model.you will have to take out dvd mech and remove disc manually,

This is a repairable assembly. It needs realigment. I have realigned many of these units with no problem as long as theres no broken plastic parts. What ever you do dont force anything.Yes there is a video input jack that can be used for hookup

power supply or power amplifire unit problem.give it to repair proffesional.

Will it not accept any dics? If so then I would recommend a DVD lens cleaner disc. Usually not more then 9.99.
Good luck,

Does sound like the laser. Realitically, not worth repairing. I'd say you'd be worth connecting a cheap DVD player to the system - then the Sony can carry on providing the surround sound audio and the new DVD player can provide the video. Then, if the cheap DVD player is still going, it can move to a bedroom TV if and when you replace the surround system....

Otherwise, I would imaging the speaker set (and even the non-working DVD player) on its own might fetch a reasonable price on an auction site - anyone who has a stolen DVD unit will probably be desparate for the speakers as Sony don't sell them separately!

mY DAV-C770 has the exact same problem ...when watching a movie it will intermittently pause or freeze ...then continue. It will do this 20 or 30 times throughout a movie. I asked a tech at Sony for help and he told me the laser reader is out of alignment. The minimum amount to have the dvd player sent out and repaired is $200.00, and thats if it does not require any parts. with a new laser reader it will be about $400.00. Almost the same price as a new dream system. Not worth fixing. I used to think really highly of Sony - until now. Jackal
