My other option was to have audio go into the hdmi cable and use the optical out that is in my tv. My only issue with that method is that only stereo ever comes out of it. I was never able to pass dolby digital or dts though no matter what i tried.
Yes that's how I have it now. I'm convinced that there is a small delay because of going through the receivers processing before going to my TV, so I want to hook the video straight to the TV. This leaves the question of what the best way to get the audio to the receiver is. I don't have any sound card, not even onboard.

Oh I am sure there is a delay, when my ps3 goes into tv first then to the speaker recievers, i think it added something like a 100ms delay or worse (I can't remember the exact number but it was noticeable) compaired to ps3 directly into the speakers. I know this because rock band 2 tells you the delay of the tv and speakers when you use the guitar to calibrate the game.

I'd say get something that can spidif out and go optical straight into the reciever of the speakers, i think that would reduce it the most.

How might this work? I have a receiver that can do 5.1 but only with RCA input; i.e. if there's a special sound encoding method (i.e. Dolby surround?) I must use or if the sound cable has to go directly to the receiver from my blu-ray player or HTPC instead of through HDMI to my TV, then to the receiver.

Dolby surround and Dolby Pro Logic I/II is pseduo surround sound. The dvd/bluray player is suppose to encode the audio to consider those formats. So the sound singal it sends is suppose to be a little different (not sure exactly how), then the sound reciever is suppose to be able to figure out that sound thats coming in and know how to split it up so it uses all 5.1 speakers. Basically it takes a stereo signal and fills it into 5.1.

Dolby digital 5.1 and dts 5.1 has 5 dedicated channels of sound plus a subwoofer chanel.

Kind of true. You need an adapter to use. I have the ATI 4890 and its just an adapter that can process the sound. Something about the pins or whatever. Works great, and no delay to speak of. I am not sure if that would change from system to system and tv to tv but none on mine.

EDIT: I forgot. I have DVI hookup but not HDMI. So what I did, was buy a DVI to HDMI cord to work. And THAT didn't play sound. So I had to get the special DVI to HDMI adapter for my card so that it would process the sound also. Thats what I was on about. Sorry for confusion.

Ok not even onboard sound, now I am with ya. OK, so your TV must have RCA outs. You can use those. I am sure there are a number of hookups that you could use, especially involving a receiver. If I were you, and probably the easiest way and still keep your surround, would be to link the video via HDMI, and just hook the receiver up to the TV as well via RCA's or hi-def sound cables through the audio out on your TV.

EDIT: Whats the model number of TV and receiver, that would help and I could tell you exactly how to hookup?!

My receiver is a fairly high end one, it can take every input known to man, and a few more. I'm just about to leave work, I'll check the back of my TV when I get home, not sure of the exact model, but it's a 47" sony bravia. I'm pretty sure the TV doesn't have any audio pass through, just the RCA to use external speakers instead of the built in.

So to be clear, can I get real surround with just two RCA ports? I'm a little doubtful of that, but if you guys say so... lol.

Yep I am pretty sure of it, but I will say not 100% positive. Like was stated before I believe the Dolby is filtered at the receiver. All it is is splitting the sound channels and sending them to their own channels and a sub.

I guess there's only one way to find out... if that works then it will be perfect, since all I would need are RCA cables.

Your TV will almost definitely have RCA-out.
I'm also curious to know whether RCA can carry surround. I guess it makes sense that channels can be mixed into one signal, then separated at the receiver.
