surround sound speakers... what do you recommend?

I am looking to get some feedback from you experts on my home theater setup, specifically I want to add surround sound speakers. I use this setup for TV/DVD and Music.


My current setup:


1) Denon AVR 1602 Reciever

2) Dell 32†LCD HDTV

3) Klipsch RF Floor-standing speakers

4) Sharp DV-S1 DVD Player

5) XBOX



1) I would like to add two surround sound speakers to this setup. I am looking to put these behind my couch and somehow hang on the wall. I would prefer if these speakers were flat (like a picture frame) and not too big. Lastly, and since I am renting, I would prefer they not be put in the wall and instead need to be hung somehow - and I would like them not to be too big/noticeable. Suggestions?? Is it ok if I go with a brand other than Klipsch? Can I get speakers that don’t require any speaker wire and are somehow wireless? What models/brands do you suggest?


2) DVD Player –is this the best? Should I invest in a new one? When I bought it, it was fairly cheap and it seems to play the DVDs just fine. I also hear there are new High Def DVD players coming out soon??? What is the deal with this?


3) Sometimes when I watch TV (I have an HDTV box set from timewarner in NYC) the sound is delayed by like ¼ - ½ a second from the picture. This happens every now and then I notice… why?? How can I fix this?


Thanks in advance for the feedback.
