hooking up 5.1 surround with DVD or Pc to receiver

[Evander]

I have a jvc rx-668vbk receiver, and its 5.1 surround inputs are of the 6 individual rca cable input variety.

My dvd unit has stereo rca out (which is how it's currently connected), it doesn't have the 6 rca outs but instead a single coaxial digital audio out (my receiver has no such input). Is there some adapter cable for coaxial digital out -> 5.1 rca in to get 5.1 sound or am I out of luck?

Also my sound card (sb live! 24 pci) has surround outputs but they are not rca out but the 1/8 inch headphone jack style (line 1 out is front l/r, line 2 out is rear l/r, line 3 out is center/sub). Currently I just have only line 1 out to my receiver using a "1/8 inch stereo headphone jack to l/r rca" cable. To get 5.1 do I just use 3 of these cables? (1 for each line out of my soundcard). If so, for line out 3 does the red rca cable go into the receiver "center" input and the white into the "sub" input or is it the other way around?

According to the specs this receiver only supports Dolby Pro Logic. You should consider getting a new receiver.

The job of Digital->Analog RCA is one of the main purposes of a receiver. So you are out of luck if your receiver doesn't have that.

And yes you can hook your computer up that way. I used to just run the speaker test until the test tones were correct to figure out which color went to what.
