DTS-HD Master Audio / Dolby TrueHD / PCM 5.1

I have a DVD player that has HDMI connection.

If I wanted to get the best movie sounds coming from the 79, do I use the single coaxial cable, optical cable or HDMI cable? I have a receiver that will take HDMI connection. Right now, I have connected the 79 with the single coaxial for sounds. I then connected the HDMI cable from the 79 to the TV. My TV also got HDMI connection on the back.

Or do I connect the 79 to my receiver with single HDMI cable to the receiver and then from the receiver to the TV?

I just wanted to know which is the best way to get the best quality sound and picture from the 79.

Thanks for any advice!!!

You listed them in the order of my preference.

As far as your DVD player, the audio will sound best through the coax or toslink, not the HDMI. Your Bluray player will however sound best when playing the high-rez formats (and only make sound)through the HDMI. If your watching a bluray with only standard DTS/DD soundtracks it may be worthwhile to A/B with a Toslink/Coax and see which sounds the best to you.

I have the Pioneer Elite BDP-05FD and I am confused about the HDMI Audio Out part of the setup. Right now, I have it setup to AUTO because I wanted to hear DTS-HD Master Audio. If I set it to PCM, do I still get better quality of sound from DTS-HD Master Audio?

PCM will remove DTS-HD Master Audio and Dolby TrueHD and revert to the older DTS and or Dolby Digital formats.
