Looking for an expert or someone with HDMI connectors and an A/V receiver to explain how they work together.

Lets say you have an HDMI DVD player or similar and you want to send the video to your display (e.g. projector) and your audio to your surround sound decoder (A/V receiver).
1) Can audio and video be split at DVD player (using a HDMI to DVI and optical cable?) or do you have to/should you send the complete HDMI to A/V receiver first?
2) If yes (you have to send HDMI audio and video to A/V receiver) can you then send just video to your display? If yes do A/V receivers even have DVI outputs?

Please no replies about the quality of HDMI vs DVI or component, this is not about that - cheers.

If you have a HDMI capable receiver like the Denon AVR-4806 or Yamaha RX-V4600..

read about them:

... then take the HDMI output from the DVD player or Set Top Box (STB) directly into the receiver. The receiver has outputs that will then take the audio and video to the input on the television. Of course, the television will be turned down or not have speakers, so the A/V receiver will handle full audio duties.

If you do not have HDMI inputs on your receiver or are using DVI, then take the HDMI/DVI directly to your display device and use the Toslink or S/PDIF connections from your DVD/STB to the receiver.

1. No, don't split it, there is no advantage to audio on an HDMI cable over audio on a Toslink or S/PDIF cable and you are more likely to introduce problems by trying to find a 'splitter'.
2. Look at the receivers listed above - nothing is 'cheap' for DVI/HDMI in receivers yet. Maybe in a couple of years it will be a sub-$1,000.00 inclusion.

Thanks for the info.
Unless I need video switching, I prefer to use my A/V receiver for audio only so good to know I can HDMI direct to display and still Toslink audio to receiver. I'm looking to buy an A/V receiver and didn't want to get stung by another connection type or signal format change. Will simply ensure my next display has at least two HDMI inputs.
It's the Denon AVR1705 A/V receiver I'm looking to buy - nice.

Gemini - one of the big deals with HDMI & DVI is that there should be no signal loss ever along the cable.

With analog signals, like component, s-video, and composite, any connection you make could potentially harm the image.

It is not something you should EVER have to worry about with digital video (or audio). People talk about the 'extra converstion' used in a Toslink connection, but this just is not an area of potential signal loss unless poor manufacturing/engineering was done.

Likewise, with HDMI/DVI you should never - EVER - have any loss, or more specifically, change, of any signal data no matter how many connections you make. Is it possible for a well engineered DVI/HDMI piece of gear to introduce interference when used with halfway decent cables? In my opinion no. Working with firewire with video for a few years leads me to believe that even in the most basic of digital setups, no matter how many copies or connections there are, the data is all zeroes and ones, and will arrive at the destination identical to how it was transmitted.

I will eventually make the DVI/HDMI jump, but I will probably wait until after HD disc players are out.

Yeah so HDMI is a good thing, just might have been easier if manufacturers had gone straight from composite to HDMI rather than the long way round of S-video being best then component then progressive component.
Even with audio you'd think the need/benefit for pro-logic II would have been obvious from the start.
Thanks for help
