Since I'm in the market for entry level DVD-A players I've done some research and learned quite a bit. It looks like there are several players available for under $200 that offer multi format capability. Of particular interest is the Pioneer DV-578A @$149. Anything I should worry about with this particular model?

Also, what exactly are the bass management issues I keep hearing about? I'm under the impression that the HT receiver would handle boost/cut and phase. Why the need for the player to do it as well?
