Digital audio problems

The optical connection (SPDIF) doesn't have enough bandwidth to transfer DTS-HD audio. To use DTS-HD, you must connect the blue-ray player and receiver via HDMI cable.

Each DTS-HD audio track on blue-ray includes also "normal" DTS audio, which is probably used when you select PCM. Player decodes it and sends decoded (non-HD) audio via optical cable to receiver.

HDMI signal from DVD can not be down converted to analog component signal.
Connect your new DVD to a component input 1..4. Make sure that component input assigned to desired input (dvd/vcr/sat/) (setup - input setup - input - component assign - component x etc). Connect coax output of DVD to coax x input of the receiver and assign it (setup- input setup - "input" - digital assign ..). Probably you need to setup DVD output resolution to 720i or 720p in dvd setup menu.

Receiver does support 3x component inputs and one component output. Both these can carry only video signal, not audio. So you have to connect audio separately, either stereo via analog 2x RCA connectors and digital SPDIC via optical (2x) or coaxial (1x) cable.

You can connect PS3 video via HDMI to receiver and from receiver via HDMI to TV. But RX-V365 doesn't support HDMI audio, so you have to connect audio separately via SPDIF digital cable. I think PS3 uses optical SPDIF, so you will need optical cable. If you can't find cheaps optical cables in your shop, you can try byuing from ebay ($1-5 max.)

There are several video and audio inputs named DVD. For video you have HDMI, component and composite. For audio you have standard analog stereo and digital coaxial spdif input.
You need to configure the receiver to use the correct inputs - that means HDMI and coax. Also you need to connect the BD player via coax spdif cable to the receiver, because rx-v365 doesn't support audio via HDMI. If BD player has only optical output, use DTV/CABL HDMI input and DTv/CABL Optical input on the receiver.

its not how there connected its in your settings. rehook up all your speaker connections properly,then make sure you proram the reciever to recieve fiber optic,hdmi,digital coax etc in the reciver.

It's the other way around.

Hook up the Cable box to the Amp; and the blu-ray to the amp, then connect amp to LCD.

you want to use the best available options for audio:
HDMI > Digital Optical > Digital Coax > standard RCA

And the similar for video:
HDMI > Component > SVideo > RCA cables

I would connect Blu-Ray via HDMI to Amp, and Cable box via HDMI to Amp. If your cable box does NOT support HDMI, but you have an HD package, ask your cable company for an upgraded box.

For this Sony, you have to use separate audio cable(s). Either optical in BD or Digital Audio in DVD (single coaxial cable will do the trick) I bet the display says UNLOCK. I had the same problem, very dumb.

Good day!

Put your optical cables into the amp and not the tv,also make sure the ps3 audio is set to bitstream.
hope this helps.

Is Yamaha HTR-640 a receiver? Try HDMI from PS3 to receiver or Sony HDTV. If HDMI from PS3 to receiver the you need and HDMI from receiver to out Sony HDTV. You could connect everything to receiver and HDMI out to HDTV. You can not have an HDMI cable AND an optical cable coming out of the PS3, only one or the other.
