I just couldn’t stand having that 1080P / 24 function on my VP and not be able to use it with my current 720 projector, so now I have a 1080P projector in the mail to me (Panasonic 1000U). So now I’m wondering how I should set things up when it gets here. I’m using an Oppo 970, PS3 and HD-AX1 into a VP-50. Then from the VP to the projector (everything is HDMI).

I’ve noticed that some BR disks say they are 1080P, some say 1080i. Same with HD/DVD.

Are the ones that say they are 1080P really 1080P, or is this some sort of marketing gimmick?? Come to think about it, I don’t even think my SD dvd’s say 480P.

I know what to do with the VP-50, but what about the PS3 for Blue Ray disks? (1080i or P) And if I upgrade to a HD-AX2 in the near future, what output on that one should I pick? (1080i or P).

Over 95% of Blu-ray and HD-DVD titles are 1080p24. There are a handful of titles for both formats in native 1080i. Those are typically the music / concert disks.

I just read this article at Secrets, and while it did explain cadence to me (I finally get 2.3!!!), I think in general, I’m more confused now that before.

After reading it, it would appear to me that film is shot in 1080P/24, then interlaced to 1080i/60, then de-interlaced to 1080P/60 and stored on the disk. Did I get that right??

Man this stuff makes my head hurt……

No, it is stored on the disk as a "native 1080p/24 film stream". Here is a excellent post that describes 24p decoding (from the disk) and 24p output (to the display).

The entire thread is worth reading.

Thanks for the link. It’s way over my head, but I’ll read it a couple more times…..and it’ll still be over my head. :)

In summery, it would appear that I am better off selecting 1080i from both the PS3 and X1 and letting the VP-50 do the de-interlacing.

Wow, what a mess though. I don’t know why these HD players don’t just decode the 1080P/24 stream instead of going through a bunch of extra gyrations. Seams like a heck of a work around to me….

Wow, what a mess though. I don’t know why these HD players don’t just decode the 1080P/24 stream instead of going through a bunch of extra gyrations.The PS3 does do that, then it applies 3/2 pulldown to output 1080p60.

Some players output 1080p24 directly, but the PS3 is not one of those.

Acording to some of the pretty smart fellers that posted in the thread (linked to above), none output a clean 1080P/24. The X2 and PS3 are scheduled to receive firmware upgrades that will enable that feature. But promised firmware is just that "promised". I've learned to not hold my breath for firmware upgrades.

Acording to some of the pretty smart fellers that posted in the thread (linked to above), none output a clean 1080P/24.I'm not sure what post you are referring to. The Sony and Pioneer BD players, as well as the PS3, read the 1080p24 source straight off the disk. The Sony and Pioneer players will output this original 1080p24 signal, whereas the Sony does pulldown for 1080p60 output. The Sony PS3, as a PC-type design, also has to do a few extra YCrCb -> RGB and RGB -> YCrCb conversions which today results in the loss of peak white and BTB picture information.

The Toshiba XA2 is able to correctly perform inverse telecine to reproduce the original 1080p source from the 1080i signals probably >99% of the time. That particular scene in MI-3 is apparently in the <1% that it cannot.

It must have been post # 21 that gave me that impression. Post 33 pretty much says the opposite.

Too much information…..

So to my original question, what output should I select on the X1 and PS3 going to my VP-50 if I wish to send 1080P / 24 to the new projector?

X1- 1080i
PS3- 1080P/60 or ?
