How do you buy an HDTV from Amazon?

I was just planing on feeding it audio from the TV with an optical cable. I was concerned about the audio being ahead of the video. Does that usually not happen?

If you run optical from the TV to the receiver you won't get surround sound. You'll get straight stereo without even a subwoofer channel. It's best to run audio from each source device to the receiver.
In either case you shouldn't notice a delay in audio or video, but if you do the receiver may have a timing adjustment.

I didn't know that. Is there any rational reason for this? The optical cable has plenty of bandwidth for DD or DTS. Why wouldn't the full signal be sent back down to the receiver? Is it a lag issue?

I've always assumed it was some crazy law or general agreement among the manufacturers to intentionally limit it. I'm sure it somehow infringes on their rights to sell you more cables or a pricier receiver.
But I think I'm wrong. Just for grins I looked up the manual for the Vizio mentioned in the first post, and it looks like it actually outputs 5.1 over S/PDIF. If that's true then maybe they've just been using cheap chips in the past and they're finally fixing it.
Just make sure you check any TV you're thinking about buying before planning your audio system around it.

Believe it or not a lot of TVs, even if they have a coax or optical out, only put out 2.0 audio thru the s/pdif connector. Some will do 2.1, some will do 5.1, it's all in how the manufacturer does it.

Love the beige sockets with the white face plate. [/sarcasm]
There's better temporary solutions to hide TV wires than cutting holes in the wall for 3 feet of cords...

Is this where I post the applicable part of NFPA 70?
