It all depends on your budget (including speakers), your room size, and what performance you hope to get from your system. You can't really choose a receiver in a vacuum of information.
I have a panasonic big screen tv with a pioneer 1015tx receiver and 5 bose speakers. DVD works great with surround sound. TV only get sound from 2 or 3 front speakers and I cannot get on screen guide. Where does the tv plug into the receiver? I have lots of connections on the back of the tv. Which one do I use? DVD is currently plugged into DVD in on receiver. Cable is plugged into TV/Sat in. If I plug TV directly to receiver TV/Sat in I get no sound.
