1080p60 is definitely not compliant, and neither is 1080p30 with blu-ray specs, although many players can play out of spec material. The point is , none of those would pass verification for replication
If you put the content on DVD-5/9 media, it's known as an "AVCHD" disc or BD5/9 , but it really isn't true AVCHD
I suspect there is an error somewhere, for example, your player might be misinterpreting the signal. What software did you use to make it?
Rendering 1080p25 as 1080i50 would result pretty much in PsF, but with interlaced chroma. Though it depends on encoder. I haven't done any definitive tests.
Older Blu-ray players with Anchor Bay or HQV chips would play PsF easily, this is what 2-2 pulldown is. My Samsung P1200 with Reon chip plays it. Many modern players with less fancy chipsets do it as well. Same can be said about 576PsF25 and 480PsF30, the former can be played back by most European players, while the latter is often not cared of properly by 60Hz players. Hence, PsF is not something new, this format has been used in DVD-video before it got accepted in BD spec. Though I would prefer if they used native frame rates.
DVD9, DVD5, AVCHD, BD on DVD and AVCREC are actually different things. Here: http://en.wikipedia.org/wiki/Blu-ray_Disc#Variants Oh, and AVCHD on DVD is true AVCHD. In fact, it was the ONLY AVCHD format for about two months or so.
As I said earlier, I don't know of any software that does this, encoder or muxer. This is all theoretical (at least to me). Please let me know the results of your tests.
I don't know of any blu-ray content or hardware that is able to play this. I know some editing software is able to handle it, but I haven't used any of the older blu-ray models you mentioned. Please let me know the results of your tests, or if you even have a sample stream.
DVD9 and DVD5 usually refer to the media in DL and single layer capacity. This doesn't necessarily indicate the content or if its DVD-video
AVCHD is a real spec, and it's usually hardware encoded with a fixed GOP size, and it's independent of the media (it could be on SD, or DVD, or blu-ray, or HDD).
If you put untouched AVCHD material and only author it without re-encoding, then you could theoretically say it was an AVCHD disc. But the things that most users put on DVD5 media are usually not real AVCHD spec.
Since this is XDCAM subforum, nothing will be AVCHD. It shoots MPEG2. Hint: the "AVC" in AVCHD means something...and when you re-encode the XDCAM footage, 99.999% of the time it won't be to strict AVCHD standards ie. "not true AVCHD".

Frankly, I haven't run any definitive tests myself, I bought my BD player based on tests that I've found on some respected web-sites. But when I pause video on my BD player, it does not drop resolution in half. I know this is not a scientific test, but it gives me a sign that the player processes video as progressive
By spec, AVCHD cannot be on BD. That was the point of AVCHD: cheap media, low bitrate and simple menus for amateur HD videos.
I just wanted to correct your phrase "If you put the content on DVD-5/9 media, it's known as an "AVCHD" disc or BD5/9, but it really isn't true AVCHD." MPEG-2 HD on DVD is not known as AVCHD disc, it is MPEG-2 HD on DVD. If you like you can call it "BD on DVD", but it violates AVCHD spec in so many ways (codec, bitrate, naming, etc) that it cannot be known as AVCHD. Well, you said yourself that it is not true AVCHD.
AVCREC allows MPEG-2 HD on DVD, but I don't think that it allows 35 Mbit/s rates on this media. I guess they thought: 18 Mbps or 19.2Mbps - no big difference. But for 35 Mbps DVD media is out of question. For presenting XDCAM EX on BD one must use real BD media, and the format will be called BD, actually BDMV.
Now we are back to square one on converting 25p to 50i, and I don't have any valuable - and verifiable - input on that. Sorry to get the thread flooded. My original message was that it should be possible to use PsF, and that consumer hardware should be capable of handling it.
My idea was that PsF and 2-2 pulldown are different names of the same thing, so this, for example, should be applicable: http://www.networkedmediatank.com/showthread.php?tid=8061&pid=69389#pid69389 I cannot find the original article I've read about the BD-P1200.

What format were these streams and how were they prepared? Do you have a URL ? It's good to hash these things out, because it's good to have other alternatives/options
IIRC, The 2-2 pulldown that BD players list as their specs have to do with frame doubling 24p , not 30p in 60i - but I'm not sure on this.
Look here and scroll down to the primary & secondary video stream section
http://www.emedialive.com/articles/readarticle.aspx?articleid=11397#iif
That list isn't quite complete, note both 24p and 23.976 are allowed, but 25p is never "legal"

Blue Ray was not only developed for NTSC markets at 29:97. Pal regions use Blue Ray and those systems playback at 25fps. What ever way you get it on the disk the data has to be converted.
The only thing left to do is buy the $60 Blue Ray burner, put my EX3 footage in and see what happens.

Pal regions do have blu-ray, but none of them play at 25p.
It might play back (as I said earlier some players can play out of spec content), but it's not legal. No spec compliant muxer (like scenarist) will accept 25p streams, and it will fail verification 100% of the time. No replication house will accept 25p content on this side of the pond or the other.
The euro version is VC-1 50i
The US version is AVC 60i with (poorly done) field blends from the conversion.
I've heard of some people in the UK have made 25p "blu-ray" but it usually stutters in most players. It doesn't fall within blu-ray specs

Unless you have the ability to include AACS encryption on every disc you create, your comp won't play in Blu-ray players that adhere 100% to the Blu-ray spec. Only a small minority of players which are non-compliant, will play these homemade BD-R discs.
Be sure to test your sample/demo disc on your clients player before signing a contract to deliver on BD-R!
