Hello. I seek enlightenment on a basic question - I'm looking at the RP56 and the RP91. I don't need the DD5.1 in the 91 as my receiver has it. Reading the DVD shootout from August has brought questions to my mind: - the report indicated that the Sage/Faroudja chipset in the 56 is superior to the Genesis chipset in the 91. The test data indicates that the 56 performed better. So, I'm considering the 56 but a lot of talk in the forum here leans toward the 91 as a better unit. My RPTV is a Toshiba 56x81 Is the 91 really better and worth the extra $$ ? I can get the 56 for $180, the 91 for $425 Thanks in advance for your advice. I love this forum - every time I browse it I want to go out and buy something else!
