No sound when playing dvd

Check HDMI Sound settings:
Enter Setup menu via remote, then Func. Setup / HDMI / Audio. You can choose from Amp (sound will be played via Yamaha), TV (sound will go straight via HDMI out to your TV and not play on Yamaha) and Amp+TV (Yamaha will play the sound and also pass it to the TV).
Also what is your source? DVD or some network player? For example Yamaha cannot decode audio in AAC or other computer formats, so be sure to change the audio settings of your player to output PCM and not raw/bitstream.

well your TV has a 1920 x 1080 Pixels hi resolution is this what you mean?

I would hook up your HDDVD via HDMI to the TV and the regular DVD to Component1 on the TV,

hope this helps

Does the Yamaha have HDMI inputs? Usually you would connect the directv and dvd player via individual HDMI cables to the Yamaha (input)and then the Yamaha (output) to your TV also via HDMI.

You should not lose any picture quality from the DVD player. I am currently having the similar setup with PS3 as the Blu-ray DVD player with HDMI and a Samsung DVD as regular player with component cable to a Samsung LCD TV. Remember the quality on Blu-ray is better than normal DVD so don't expect more than what it is.

"I am also having difficulties in try to display the yamaha set up menu on the tv."
According to the manual the display menu for TV will not work with HDMI hook up.
I also have a Panasonic HD TV and can't get TV sound through my Yamaha AVR on "TV Sound" mode.  Trying to use HDMI cable for this also.  Do I need a digital optical cable or do I not have something set right?

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.

The lack of video in the DVD can be isolated to the DVD players output mode, if you are using the component video out on the dvd player then be sure to follow the componet out of Receiver to the tv component inputs, if you are using the HDMI from a DVD HDMI into RECEIVER HDMI then go to TV HDMI, you cannot mix component and HDMI on this model of AVR receiver and acheive results, in other words keep the COMPONENT to Component and HDMI to HDMI signal path, the results will be similiar quality audio and video UNLESS you are doing a blu-ray source which will result 1080P quality, all other video, HD results to 1080i, about the audio, if all 5.1 test tones are satifactory to speakers but on playback modes for DVD or HD tv signals all you are receiving is LR which is basically 2 channel (stereo) you need to enable a MULTI-CHANNEL capability input, this must be a option on the DVD Player Audio MENU output, be sure it is set for DOLBY DIGITAl 5.1 or DTS outputs, be sure to have the receivers digital input enabled if you are running optical cable or coaxial digital for the audio, you will be sending a multi-channel input to the receiver when the Receivers Faceplace LCD displays 5-6 speakers. If it shows only LR or two speakers it is not locking into a 5.1 audio input.

Sounds like a poor grounding issue between the units OR maybe they're not as compatible as the Mfg's say.

Could be a bad HDMI cable also. Most are made in the land of Nanking

best set up if you have all hdmi is to have all your components go into the receiver ie. hd cable box, dvd etc. by using the hdmi output from the player(s) to the hdmi input to the receiver. next use one hdmi cable from the receiver to the tv then your laughing.

good luck

I have the same problem with my Sharp Lcd and Onkyo 804. I believe one problem is that the TV can not accept dolby digital or dts digital audio signals through HDMI. It will play sound if it receives a PCM signal through HDMI. You can try switching the type of signal on the cable box settings and on the dvd player. I switched to PCM and got sound through the TV and the receiver. The problem is that PCM is usually only a 2 channel signal and Dolby 5.1 will sound better through the surround sound theater system. I have not found an absolute solution to this yet, but I am willing to not get sound through the lousy TV speakers in order to get top notch sound through the Onkyo.
