Can anyone recommend a DVD to help me configure my system. I have the following components Denon 2801 Definitive Technology Pro Cinema Speakers Panasonic DVD RV31 JVC 32D502 Overall I have things setup pretty well. I just think that it could be tweaked some. For instance music mp3s dont seem to have a ton of bass, but I watched "The Haunting DVD" yesterday and the bass was way too high where it didnt sound smooth or in conjuction with the rest of the movie. Anyone know what the subwoofer crossover setting does? I have it set to the middle. Also, my surrounds are not as intrusive as I would like them to be.
