Hi folks:

I'm setting up a home theatre and one of the processors I'm seriously considering is the 990. One of the other processors I'm considering is the Anthem AVM50. Aside from the obvious HUGE difference in cost, I'm rather confused about several things;

The Anthem offers upconversion of all? input signals to 1080P. What happens if my source sinal is from an upconverting DVD player or a blu-ray player already providing a 1080P signal. Which upconversion supercedes the other? What is the difference in quality between an upconverted signal say, through the Anthem vs an unconverted signal from a blu-ray player? If I'm using a blu-ray player and a 1080P projector, is there any advantage to having the upconversion in the processor? Please help.
