I'm afraid the multiav adaptor I've got doesn't have a model number on it, but it does have the official Sony Playstation logo on it, so it looks like an official Sony product.
My projector certainly doesn't support HDCP, but HDCP is only for a digital connection anyway. PS3 works fine on my projector, though I only tested it for 10 mins or so, to make sure it works. Waiting to get the cabling fitted tidily.
I tried a few games and they were OK, and I tried the Click Bluray (which was all I had at the time, came free with it) and that worked on the projector too. I did read that bluray disks weren't going to enforce HDCP yet for a few years anyway, to allow people with HD tellies, without HDCP, to be able to use them. Seems this is true, in the case of Click at least.
May be a week or two yet, but when I get the projector set up with the VGA cable again, I'll try my other blurays and games out.
The adaptor itself is a standard Sony Playstation AV out one end, to VGA
and stereo phono audio the other.
I can take a photo and upload if required, as it's not all plugged in yet.
