Thanks John for your info..

You seems to know much about the subject.. Could you tell me if i'd be doing a good buy ( again knowing it will be use with Panasonic's projector that has HDMI input.) Would it be an improove product against everything on the market?

I'm looking at the Panasonic's DVD-S97 Universal Player that has the following specification:

YCbCr Resolution: 720X480X30/NTSC or 720X576X25/PAL (progressive and interlaced)

HDMI: 480p, 576p, 720p, 1080i

Any other recommendations?
