I have a Toshiba SD-4900 which I chose in large part because it has built-in 5.1 decoding with 6 analog outputs which I need in my application (a screening room). Unfortunately this unit stutters a bit on certain burned disks (these are client-supplied and I don't know if + or - or what). I've never noticed it on a normal store bought (pressed) DVD but sometimes with client materials there are tiny glitches that look like an instance of unintended slow motion. This is a professional situation and I can't have that. Reading problems? Too high a bit rate to handle? I've no idea. I wish to replace it with one that will play smoothly. I realize there are no guarantees but some machines may have a reputation to handle everything they're fed and others do not. I'm looking for recommendations for a new player. So besides smooth, reliable playback: Required: Built-in DD 5.1 decoding (6 analog outputs) DTS a plus but not required Progressive scan & component outputs (obviously) Would also like to have: Region Free or Available hack PAL/NTSC playback with PAL or NTSC output These latter 2 points are mostly for my own personal use (I want to try watching PAL disks in PAL for the greater resolution) but the main thing is smooth playback and 5.1 out. What say you?
