Thanks to all for the respoinses.
I know that S video and coaxial are limited to 480i, however some recorders would output simultaniously progressive scan over component and/or HDMI and interlaced over the S video and coaxial. This is important to me, because I have my recorder connected to a progressive scan projector, and a regular non-digital TV. From what I've tried Samsung R135 and my LiteOn recorders output both signals at the same time, and the rest models I tried did not - Philips 3400, RCA DRC8052, and some PYE don't remember the model number.
I have already ruled out the Panasonic based on your responses. It simply doesn't offer anything to me that the PYE recorder couldn't deliver for about $50 less. I returned that one for two reasons - one was that it could not output both progressive and interlaced signals at the same time, and two was the lack of play/remain/clock info on the display. Those things seem small, but in turn reduce the value of improvement over my Lite On recorder. Its only advantages to me were its stereo tuner and its resume which worked at power off (but not if disc is ejected). If it looked at least semi attractive I might have kept it.
This goes for the Panasonic too, actually, in my eyes this is one of the ugliest recorders on the market, and combined with other missing features I am looking for I just can't justify spending the money on it.
Again, thanks to all posters.
