Sorry I didnt specify.
I have it hooked up via HDMI, and in the settings I have 480p, 720p and 1080i all checked.
I checked that thread and 300 is rated:
Demo Material, but minor artifacting may be present which the untrained eye may not necessarily spot. Little if any visible compression. Sharp image that has a lot of HD-POP effects. If you are thinking about buying a movie in this tier don't hesitate. Show someone one of these films and they'll want to join the Blu side!
This is not what I'm seeing. I get a lot of image noise. A LOT. And it moves, so it almost looks like static. I dont see it on close ups of stuff, but in the background it is very pronounced. Like the sky or skin are the worst. It looks like tiny bugs are crawling all over. Film grain I can understand, but this just looks wrong.
When I put 300 in for my friends, we all looked at each other and sort of went "Ok, this cant be right". Not some thing I would want to show off as my new expensive toy, thats for sure.
I did some more forum reading over the net, and I managed to clean it up a little bit by turning noise reduction off, and setting "sharpening" to 0. But its still not a "omg amazing picture". In fact my HD cable channels all look much cleaner and don't have the noise.
Right now I would say that my Blu-Ray image seems about on par with a DVD being played on the Xbox 360. Maybe just a tiny bit more crisp for close up images. Also, normal DVDs dont look very good on the PS3. The xbox 360 connected via component looks better. I tried Xmen2 and 300 in normal DVD, and Xmen was passable but not great, 300 was HORRIBLE. It was almost unwatchable on the PS3 I had an amazing about of artifacting, and every thing had the "halo" effect of an image being blown up to big.
Could the PS3 be downgrading my signal, and since I have an XBR, the TV be upconverting the downgraded signal? Thats the only thing I can think of thats making 300 DVD look so horrible.
I am going to swing by Blockbuster and try and pick up some of the Blu rated movies from that list and check more tonight, but seeing as 300 was a Gold rated movie, I am not hopeful.
