I must say this player has fantastic up conversion. I've used some supposedly good players for upconversion before, the Toshiba HD-A1, the Samsung BD-UP5000, this one still bests them all. Tried watching my old Devil's Advocate DVD on the Panasonic today, looked all blurry and poor, tossed it on the BDP-S1 looks clean and crisp, almost well enough to suffice until they finally release the Blu-ray.
The difference is so great that I'm actually considering buying a used one strictly for DVD viewing over the BD-UP5000. Anyone else feel the same about this one?
