Purshased the 4677 last month. Works great out of the box. Would like to replace my Sony DAV-C700 all in one set up with something newer as the dvd player is rather weak, ( squiggly white lines on my kids sponge bob DVD's) Any reccomendations would be help full. I plan on placing the new unit(S) in a cabinet with height restictions of 4 1/4" and 6 1/4". Also the surround speakers need to be upgraded. I've looked at the other forums on this site and haven't seen anything that seems to be the right answer for my setup. Thanks for the help!
