I have a Panasonic PW6 and I output scaled output from my G91. It looks great.

There is a lot of stuff over at www.avforums.com about this and I think you are incorrect when you say that your panel can't display 576p natively. I'm pretty sure that this is what you'd actually want the player to output.

Whatever the technicalities I really can't see any problems with the image on my screen when outputting 576p. Can you?
