Re: Playstation 3 as Blu-Ray player.
I must comment....
I agree scaled SD DVD's can look pretty good, but if your set does 1080p, and I suspect yours does (could be wrong here) you only need compare an SD DVD scaled to a Blu-ra (or HD DVD but as we are speaking of PS3) to see the difference, it is HUGE! I have both the SD DVD and Blu-ray of "Pirates of the Caribbean Dead Mans Chest" and have used these to demo high def discs to several friends on both the Samsung BDP-1200 and Sony BDP-S1, both very good Blu-ray players.
Well, even my 'sit and wait out the format war' friends ended up buying a Blu-ray player after seeing this demo, it is night and day how much better the picture is, and it should be easily appparent to you if you do a similar demo.
Try it for yourself, I am sure you will agree!
