Also, the audio receiver can decode multichannel audio not only from DVD discs but also from digital cable and satellite signals. Only one tested model, the Sharp DV-710U , doesn't have component output. The Apex AD-600A has it, but it didn't yield the expected picture quality in our tests. Neither of these players would be the best choice if you want to use your TV's component inputs. If you want to connect the DVD player to a digital audio receiver, see what connections each component has.
Some players have both optical and coaxial outputs, but others have one or the other.
Receivers likewise may have only one of the corresponding inputs. Make sure they're compatible. We did consider picture quality and ease of use. A DVD player's picture quality is excellent at best, superior to any VCR's. There's some room for improvement in ease of use.
