AVCHD supports 1080p/24 http://www.avchd-info.org/format/index.html
I noticed that the initial chapter of each section of the Measure Grayscale menu (except Near White) is a 0% Black Field. This 0% Black Field is supposed to be displayed for 2 minutes, is that right?
The grayscale sections start with black and have chapter skips to move between patterns.
So maybe the BD-P1500 plays AVCHD just fine. It remains to be seen whether using this disk results in a reasonable brightness setting on my PN50A650 Samsung plasma.
I went to Circuit City today to look at the BD-P1500. They had at least two of the model on display. One played the AVCHD just fine and one did not play it at all. I don't know how to check firmware versions on a Samsung, and I didn't even try to look, but most likely different firmware is the reason why one played AVCHD and one did not. If I owned the player I would probably try to update it to the current firmware, considering the online manual mentions AVCHD support.
The player I used was hooked up to three Samsung TVs. To start the TVs were all badly clipping blacks. What I mean is that this disk, Avia II, and GetGray each showed nothing at all on the black patterns to start. I went into the player settings and didn't find many options, other than 1080p worked. I ended up changing settings on an A750 LCD. I found a setting called something like HDMI black level on the TV, and after changing that from low to normal, near-blacks showed up around the typical brightness setting with all three disks.
I clicked contrast a couple notches off maximum on the TV and the near whites clearly showed up on the White Clipping Pattern and GetGray. When there were overlays on screen I could see the above whites flash, so I figure the above-white signal was making it to the display. I'm not familiar with Samsung displays, so I don't know if there's a way to get them to display above-white and below-black. Although I never saw below-blacks, I also didn't see anything that would indicate any issues because the DVDs also didn't show below-black.
All I wanted to do was to verify if AVCHD playback levels seemed to match DVD levels like mentioned to mulox on the last page. Considering the two reports were similiar, I figured it wouldn't make sense to release a new version if there was clearly an undocumented issue with a player from one of the three original Blu-ray manufacturers. Anyway the levels appeared to match between AVCHD and DVD disks, and I couldn't find any differences that would suggest errors with AVCHD playback. Aside from the likely firmware item, it seems to me the AVCHD plays fine on the BD-P1500.
