Well I can tell you right now, there is no clear-cut leader in the $1000 range as far as receivers go. A little more info on the speakers you are planning on using and the type of tv (with ur dvd player, I assume you have hdtv..... but maybe not.).
The marantz dvd player is pretty solid. It doesn't make much sense to me to run the dvd video through your receiver, unless convenience is really important to you. As for cable/sat, I'm unfamiliar with the de-interlacing quality for those machines, especially since there are so many different boxes out there. So that leaves mostly music... I recently chose the yamaha htr-5890 as my receiver. There weren't as many hd video inputs on the yammy as there were on the comparably priced denon avr-2805. I liked this because my dvd player (the oppo dvd player.. uses same faroudja technology as your marantz) already had a good de-interlacer, and right now I don't really care about my cable, since the service around here is a joke. After my initial spec comparisons whittled my selections down to a handful of receivers, the denon avr-2805 and yamaha htr-5890 were the only receivers i was able to demo at any stores in my area, and i decided to go with the yammy. I have been very pleased with the sound and the ypao was surprisingly easy to do, considering my lack of technichal expertise. Now if only TV's were that easy to calibrate....
