 Also, are you movie buffs, combined media users? Will gaming be involved?
 Upconverting is very important and noticeable, at least to me.
 Remember to include the NON HD sources to the appropriate input on the display lest the conversion be annoying on the large screen.
		
		
	 
Thanks for the response.  The room is about 15 by 12, with a couch about 7 feet from the screen.  There is not much room in the back to mount speakers or to even run cables because the back of the room is actually a large opening to another room, and the walls are obstructed by large French doors.
My parents are the ones buying the TV, and they actually don't watch much (movies/tv/etc) at all.  But they do listen to lots of music.  Gaming will NOT be an issue.
I'm not sure I understand what you're saying about the nonHD sources and how to connect those.  Please clarify if you get a chance.
Thanks!
		
 
		
	 
 By using the setup feature , you would be able to adjust the rears for optimum performance, even if the geometry isn't congruent.
 Rear speakers, even while listening to music can be advantageous. The matrixing constructed by the DSP can expand the sound field and keep levels at a reasonable level.
 Subwoofers can be had very inexpensively, and are necessary if movies will be watched, Same for center channel.
 I would rather have 3.1 than plain old stereo if given the option. Dialog is directed to the center for clarity and any summing / difference effects are PSYCHOACOUSTIC in nature. This is the same arguement some use against BOSE speaker processing. If it's BAD JUJU for BOSE, why does it become GOOD MEDICINE for another manufacturer?
 HD programming is all digital. Lets call it a round pipe. Analog and Non HD Digital is the square peg.  The HD input is the ROUND Hole, The other (svideo, component, Composite) are the Square Holes. If you watch Non HD sources through the HD inputs, you will see artifacts that are not there when the NON HD signal is brought in through the other inputs. Think of that square Peg and round hole. It is possible to insert said square peg into the round hole, but only portions of the square peg will contact the sides of round hole. Up conversion of these Non HD sources will improve, but the current state of the art isn't there, YET.
 Route the HD sources into the HD inputs and the other sources into the component inputs if UPCONVERSION is available through the receiver.
 If those French Doors are between the two rooms, you can expect a dramatic difference in the room 's response depending on if they are open or closed. This may actually push one to work a little harder to include the surrounds as they will bring the sound closer to that room and allow levels to be kept at less than ear bleeding, depending on your parents type of "listening" i.e. Background, Foreground, Exterior Noise masking, etc.
