Reading your provided link, it comes down to the ps3 not being on the list of players that support internal conversion according to someone in that thread that posted a link to players that will/will not play any fps/hz discs. apparently it's a cost cutting issue. seems fitting sony would do this to the ps3.
Course, i didn't look at the player list. I don't care. I don't want a blu-ray player because everyone i've seen SUCK. Mostly due to the standards/implementation of Blu-ray. I've bought one or two Blu-rays from Amazon UK because the US version either weren't available or were done very badly. A current one i'm might buy is Star Trek TNG. I've had no issues playing in on my PC directly from the disc. No ripping, no conversion. I unfortunately don't remember which one(s) they were so i can't check much of anything. Wonder if Amazon UK order history is separate.
Edit: most recent was the Harry Potter blu-ray set.

Nothing about PAL/NTSC or fps.

probably doesn't help, but i can post the info from one of my x-files disks i'm currently watching.
Edit2: oh, maybe someone following this thread in the UK that has this set can post what info they get from their player?
