Are all Coax digital transports the same?

I've recently found out about how toslink digital adds jitter, and the problems it puts into the music.

So I saw my DVD player has a copper, coax digital out. It's a cheap DVD player, about $40. But would it be a perfectly faithful transport (assuming I have a good cable) for CD into my receiver for DAC'ing?

Dne - That's the Toslink I'm using. I bought glass one just in case (Benchmark doesn't care) and found it to be very high quality product for a fraction of a cost of others.

Yes there is no difference in audio components and cables!

Well, I found one difference. My Sony $40 DVD player will play a CD fine, but it will not send my DTS 20-bit 5.1 channel DVD-Audio CDs out through the coax digital out. But my friend's $130 Yamaha DVD player will send them to the digital coax out just fine. And perfectly, as far as I can tell.

Which leads me to wonder if the 20-bit DTS DVD-Audio CDs just simply have "more information", and require "harder working hardware" to deliver.

Any thoughts? Also, does anyone know what feature I'm looking for, that will send digital out multi-channel?
