My older Sony A/V Receiver has inputs specifically for dolby digital 5.1 audio (front-right, front-left, center and subwoofer). My DVD player has component A/V outputs and a digital audio output (coax). How do I connect the two in order to take advantage of dolby digital 5.1? Don't get me wrong, I've connected the two together using composite A/V cables and it works fine, but I feel I'm missing something by not taking advantage of my recevier's 5.1 feature. Your time and response is greatly appreciated.
You know, I'm betting those inputs are actually outputs. The whole purpose of a 5.1 A/V tuner is to be able to split the digital signal into the 6 output channels. What is the model number of your receiver? It should at least have a coaxial connection for digital audio input.

Sorry, I'm not at home and can't remember my receiver model number. From what I recall in looking at the owner's manual last night, the hook up example shown from a DVD assumes that the DVD does not have a built in decoder, therefore, it requests that I hook up the DVD to a decoder and then the decoder is connected to the recevier.
The receiver should be the decoder.
Post the model number when you can and I'll try to help more.

I will, thank you for your time.
No problem. Welcome to A2K!

My Sony recevier is Model STR-DE625
OK, sorry to tell you this, but your receiver doesn't have a build in decoder. See page 8:

I think the best thing to do is bite the bullet and buy a new receiver. Things have changed a lot in the last couple of years.
Your receiver doesn't have it's own internal AC-3 decoder (and no digital coax or optical input). AC-3 (aka "Dolby Digital DTS") is a newer standard for 5.1 (5 channels + sub-woofer) digital audio. (FWIW, AC-3 isn't even a fully approved standard yet so "AC-3" devices aren't even all compatible with each other.)
You can get the same effect by using the L/R audio jacks, 5 speakers and the Dolby ProLogic setting (which is 5 channel audio). Dolby ProLogic on your receiver is set by using the "wide" surround mode.
You could spend the $150 or so on an external AC-3 5.1 decoder, you could buy a DVD player that has it's own built in decoder (some models do have this.) or you can replace your receiver to one that has Dolby DTS Decoding but I doubt you'd notice any difference in a typical living room if you don't have a sub-woofer.
Looking further at the manual, fishin' is correct about getting 5.1 sound by simply using the L-R audio inputs and the DBS setting (why they use that acronym I'm really not sure).

I think they are referring to a connection of a "Direct Broadcast System" (i.e. DirectTV) to the receiver.
Man, I'm really confused today. Sorry.
