BD-Audio is a standard format, I don't know about photos, though they can easily be emulated with the Bluray menu system.

I always thought there are some undocumented disc formats for PS3 this is why i speculated if BD discs with rco's are suported in PS3

BD menus are completely different to how UMDs work (Java based system), so no, you won't find any RCOs there.
The design decisions for UMDs and BDs are completely different, so one shouldn't expect many similarities (beyond playing videos).  For one, BDs are completely incompatible with what the PSP can do, ignoring the different physical format.

PS3 games may be a different thing, though until someone has seen it, I'd say it's unlikely too.

Thanks for putting up that list.
I'm not sure how useful it will be though.  I've never seen the value have much effect.

I don't have a dump of FW6.61 handy so I can't check easily, but I wouldn't be surprised if it hasn't changed.
