Hello. Can some please help me on which model to have? BDP 450 or LX55? Does both give good viewing? Dealer don't seem to help on what is good Some reviews online give 4 and 5* on both machines. I had a Panasonic 3d bluray player which was under 2 year warrentee. I got some money back on it. So looking at Pioneer 3D blu ray. I'm using Panasonic 50VT30 Plasma. Also have media files on MP4. Checked Spec on LX55, does not state MP4. Thank you. Victor M.
