First time poster, long time reader - off and on since the early days of dvd. I am currently entrapped in an upgrade cycle. I just purchased a Denon AVR 5800 to replace my Yamaha DSP A3090. With that upgrade, I feel I am in pretty good shape (8 Mirage speakers, Electrohome 4100 CRT Projector, IEV Turboscan line doubler). However, my current DVD player is the Sony S7000 (oldie but goodie)and the only complaint I have is that it does not output the DTS bitstream. So I have considered upgrading (right now I am using my SP2 for DTS playback). I have read all the glowing reports and recommendations for Panasonic RP 91 and it sounds like a great machine. However, I really don't need the scaling feature because I am using either 4:3 or 16:9 mode from my projector. I also question the need for onboard decoders because I have that capability with my receiver. Finally, I question the need for progressive scan since I am already getting a doubled (progressive) picture. Now for the questios (thanks for the patience). Are my assumptions correct. If they are, what DVD would you recommend? Thanks in advance for the help.
