I don't know the JSD 80D, but I can answer the first part of your question.
The digital Co-ax output on DVD players is SP/DIF, so if the JSD 80D does have SP/DIF inputs then you would be able to play DVDs through it. Whether the JSD 80D can decode Dolby Digital from such a source, I don't know. If it can then you will get the full 5.1 channel sound from the DVD (assuming that the disc you're playing has a 5.1 channel track of course)
If the JSD 80D can't decode Dolby Digital from a SP/DIF source then you would have to configure the DVD player to decode Dolby Digital to PCM, and feed this into the JSD 80D. However, PCM output from DVD players is only two channels, which can be matrix decoded to give L,C,R and S, as with analogue Dolby Stereo tracks on 35mm film. As an alternative, some DVD players can decode Dolby Digital to six analogue output channels; if the JSD 80D has six channel analogue inputs, then you could do it this way.
