Laserdisc Dolby Digital and DTS
I've got a question for all you Laserdisc diehards. I'm thinking of picking up a laserdisc player on Fleabay and I had a question.
If the player has an optical digital output does that mean I can play DTS and DD discs without an outboard decoder? If my reciever has DD and DTS decoders built in will they do the trick or do I have to have an outboard converter?

If the player can pass the signal then your receiver should be able to decode it. I would check the specs of the laserdisc player in question carefully to be sure this is the case.

LD players pass DD signals through an RF output, so it would have to have one of those (and be labeled "AC-3" or "DD") to pass a DD signal, and even then you would need a receiver with a LD-specific RF input.

dts will be output via an optical output, but not DD.
DD/AC-3 has a dedicated RF output for that purpose and you'll need an RF demodulator as well, unless your processor/receiver accepts an RF signal.

There is a FAQ on my LD page that may help with some of these questions:
http://www.mindspring.com/~jzyber/askjosh.htm
In a best case scenario, an LD player should be connected to a receiver THREE times:
- Analog L/R cables for the analog audio tracks (this signal cannot be passed through a digital connection). Audio commentaries are stored on the analog channels, and some very old discs may not have digital audio at all.
- Digital connection (optical or coaxial) for the PCM digital audio channels or DTS.
- RF connection for Dolby Digital 5.1. Must be connected to an outboard RF-demodulator then to the receiver.
Complicated, yes, but worth the effort. Laserdisc audio is widely regarded to be superior to DVD sound quality.
