US and JAP PS3 got full hw backwards compatibility ie both chips on the boards, but the EU is emulating one chip and got the 2nd chip on the board.
 
I've got a EU PS3 as well. Anything I can do to test? I've got a fair few PS2 games still (they're pretty easy and cheap to come by too). But like grandmaster, I might just as well not have any because after the first year I've never booted another PS2 game. Too many great PS3 games to play!

Yes the EU 60GB model is nearly unplayble with F1 from EA, GT4 too ... it must be cca 300-500ms for F1 and cca 200-300 for GT4

I think this depends on the monitor but I am not totally sue. I remember playing Tekken 5 at a friend's house and there was lots of lag between input and screen action.

I didnt notice any lag when I tried GT4 though on my TV but probably I havent tested it much

i think not ... PS3,X360 games like GT5P,KZ2,GeOW2 even Super Stardust HD etc are OK ... i have Pioneer 5090 with GAME MODE ON ...

What I am saying is that possibly some PS2 games might lag on some monitors when plaid on a PS3.

I tried GT4 afain on my PS3. There wasnt any lag at all.

I ll check Tekken 5 sometime to see if it lags on my screen. But then again even when you play T5 on PS2 it lags on some LCD tv's. A lot
 
Update: The PS3 certainly is full of surprises, and looks like I'm a bit ahead of my time with this demo. Turns out that while 1080p60 decoding is supported, the PS3 then goes about forcing the image to work only on a 1080i display. Force 1080p, and it then upscales the "nerfed" image! It took a while to figure that one out, especially as it defies logic: the PS3 is in effect adding to an already massive CPU burden by going through this bizarre process. So, for the time being, the raw video is supported but the displays are not... once there are more cameras like Sanyo HD2000 on the market, expect this to change.

I seem to remember that almost no TVs can handle the bandwidth for 1080p/60, so maybe the PS3 has as default behaviour to take that into account. Strange though, but yeah, like you say, sounds like its intentional for current LCDs and it might change at some point. Still weird though because on my computer screen it seems like 1080p/60 works properly in games, even with the screen having to scale the 1920x1080p image to 1680x1050 (which my LCD does even though it initially says it can't handle the signal, which is quite odd).

You might be right. I was reading reviews on HD camcorders and came across this blurb:

"One of the reasons why neither Panasonic nor Sony has committed to 24Mbps (as opposed to Canon, who've pretty much standardised this) is that the higher profile / level can't necessarily be handled efficiently by other devices such as LCD displays or disc/hdd media players. I'm told that engineering tests have shown this to be the case, despite the fact that Canon has jumped the gun on this one. That's why Panasonic has kept its celing at 17Mbps for now"

So it sounds like the behavior is intentional to maintain 100% compatibility with current tv's.

That shouldn't be necessary. The HDMI handshake would let the playback device know the formats the display device is capable of accepting.

Edit:Out of curiosity, when playing back 720p content and forcing 1080 output does this also output 1080i?

OT, the 24mbps in camcorder is usefull for quit a less compressed data, is goal is not for show directly on TV, but for edited video with software.

Maybe some tv's lie/exaggerate their capabilities? As in maybe some report 1080/60p support erroneously. I don't know too much about the tv hardware world, but on the PC side, incorrectly reporting capabilities on video hardware has happened many times in the past.

True, but those higher bitrates do currently have some disadvantages. I use two Sony HD cameras for a side business at AVCHD 16mbps, and I can natively edit all the footage from that camera on Vegas 9 which saves me tons of time. I hear it's not the same with some cameras at those higher bitrates or apparenly on Macs, that both need a transcode step which would be a huge time waster for me. Plus the Sony's seem to review well at that lower bitrate, whereas other higher bitrate cameras don't rate as well. So I'll stick with good optics+native editing :)

I'm thinking in this case the fact that they are trying to play back a non-spec compliant Blu-ray disc is more responsible for this than that they have deliberately gimped the playback for people who's hardware is designed properly to accommodate those whose hardware is broken. At least I'm hoping that would be the case.
 
It's interesting, I still play TV and I feel somehow forgotten, super sampling is nice but clearly most of the time text are close to unreadable as well as mini map.
It won't happen but I would like to see the ps360 pushed while rendering way fewer pixel they may reach crisis quality at SD resolution.
