I am considering these two players, Pioneer DV563A vs Onkyo DVSP501. My main consideration is Progressive Scan capabilities. The Onkyo would compliment my NR900 and allow for automatically switching to the DVD input on the NR900 when the 501 powers on. The Pioneer offers SACD and DVD-Audio. I would like to hear comment as to the Progressive Scan abilities of each player as well as the quality of each. Thanks for any input.
