I'm willing to spend up to $300 on an upconverting DVD player. I have a Panasonic PT-56DLX75 56" DLP and a Yamaha RX-V800 AV Receiver (4-5 years old). I've heard good things about the Panasonic DVD-S97S and the Oppo DV971H. Any recommendations for the equipment I have? Oh yeah...what is "macro-blocking", and in what situations would this occur?
