Some equipment questions...

[ZackL]

My mother has a very decent dedicated home theatre in her basement. It's set up with 7.1 Paradigms, RX V1700 receiver, a 720p Panasonic projector. She knows NOTHING about what she owns and listens to the advice of her ridiculous friend who helped her set it all up and thinks the guy is always right. In truth, when I asked him why he didn't set her up with BD or a 1080p projector ( she had a $25,000 budget and could easily have gotten one) he didn't know what I was talking about. So I just have a few Qs:

1. Will the RX V1700 offer her HD sound if she purchases a Playstation 3. From what I understand the PS3 will do the HD codecs and simply send them to the receiver instead of the receiver doing it?

2. Should she be getting a screen for her projector? Currently she projects onto a white wall. I assume that a screen would benefit her.

3. She likes to use the " Enhance " button on the receiver, which essentially takes the speakers that should be used as background noise as main speakers. Does this not drown out the proper use of the speakers? Should she avoid doing so with her new HD setup.

4. Could you recommend a projector within the $5000 range @ 1080p.
