I am running only HDMI connections through my system, and I thought these SPEAKER SETTINGS in the PLAYER were only for ANALOG OUT connections...first, if I kept the player's SPEAKER SETTINGS on MULTI CHANNEL, and then played the uncompressed PCM track, the receiver only let me choose between two listening modes for the track: DIRECT and MULTICHANNEL. When I switched the setting on the player to 2-CHANNEL output for SPEAKER SETTINGS and played the PCM track, the receiver suddenly let me use all the DSP modes available, such as All Channel Stereo, Mono Movie, Pro Logic II, etc...all of which sounded horrible on the uncompressed track. I don't understand what is going on here....if this SPEAKER SETTINGS menu is ONLY for analog output, then why is the audio being affected when I'm connected ONLY through HDMI and I play with these settings? And then the question becomes should I leave the SPEAKER SETTINGS on 2-CHANNEL or MULTI CHANNEL?
That is how it should be. When you send discrete 5.1 channel PCM to the receiver, it simply cannot apply any of the DSP modes since they meant for 2 ch analog or PCM. So the receiver behaves as it should no mistery here. Use the multi channel mode!

You have to look for that LFE setting I told you about, and make sure it is set for the highest setting which is 0db.

I have no idea where this is...
Just checked the manual for the 605, it lacks the LFE pad that is available on higher end Onkyo models. Sorry.

if I keep the DTS HD audio output of the player on PCM instead, the receiver sees that "MULTICH" display, indicating to me the core DTS mix is being decoded IN THE PLAYER instead, and then the receiver is getting the DECODED CORE DTS MIX from the player...EITHER WAY, as was explained to me on another site, I AM ONLY GETTING THE CORE DTS MIX EMBEDDED IN THE MASTER AUDIO MIX....so, BITSTREAM sounds better to me, so I keep the DTS HD setting on BITSTREAM in the player....follow and agree, or no?
This player CANNOT decode this track period, it only extracts the core, which can be transmitted via HDMI or SPDIF[optical, coaxial] and it's bit rate is 1509kbps for 5.1 channels. It roughly equals to a CD which is about 1.5mbps at 44'khz sampling rate. For discrete multi channel PCM you would need 3x as much more data info. So when you have the "multich" appear on the Onk while you send DTS as PCM and see how many channel indicator is lit on the front panel which indicates how many channel the receiver gets.

But I don't understand; I keep the TRUEHD audio output of the PLAYER on PCM -- is this correct? -- that way it can send the DECODED signal to my receiver as multichannel...this, again, causes a lack of bass, but that's something I can't do anything about.

So, are you telling me that the manual for this player is CORRECT -- that what it is actually doing is taking the audio codecs that are set for PCM output and DOWNMIXING THEM into a 2-CHANNEL SIGNAL to be sent to the receiver? Isn't this not right, though???
BD players have secondary audio decoders built in,mandated by some of the interactive options like PIP commentaries and such, and that requires that the player mix all those togheter and then send it out as you choose them. Because of this and the fact that this player can't bitstream those HBR tracks [DTHD, DTS HD, etc] the DSP engine that responsible for tasks like bass management will be in the loop at all times, hence why bot the 2ch and MCH setting will affect the HDMI output.
