![The Descent (Original Unrated Cut) [Blu-ray]](http://cdn.avsforum.com/e/e4/50x50px-ZC-e4d4ec8a_B000JJ5F0W-51clVL2uVtL.jpeg)
UPDATE: I'm "a bit" late in bothering to update this OP, but I figured I'd better provide the most important info we gained from the thread right in the first post, for any new readers.
Screenshot comparison #1 - Both USA versions - AVC vs MPEG-2 vs MPEG-2 PiP
Screenshot comparison #2 - Both USA versions - AVC vs MPEG-2 vs MPEG-2 PiP
Screenshot comparison #3 - Both USA versions - AVC vs MPEG-2 vs MPEG-2 PiP vs HD deleted scene
If you want to pick up the seemingly discontinued American AVC version, your best bet is to go to a brick & mortar store and look for the case type - and more importantly - the catalog sticker pictured at left:
AVC case + sticker ......................| MPEG-2 case + sticker
Screenshot comparison #4 - USA version AVC vs Australia release (stylized colors)
The recommended release is the Australian Blu-ray.
Other releases that may or may not be similar and may not be Region ABC:

Lionsgate's Blu-ray of The Descent is supposed to have 3 different versions of the movie on the disc:
Unrated - AVC - seamless branching
Rated - AVC - seamless branching
Picture-in-Picture - MPEG-2 - separate encode
BUT there are also discs out there that instead have the Unrated/Rated movie encoded as MPEG-2! The different presentations have caused some confusion with people thinking others were just watching the wrong encode and complaining for no reason.
In March, jorange posted about this in the Blu-ray Players forum and was swiftly ignored.
In July, lgans316 noted this in a thread about a separate issue, and has been a bit more vocal about it. 
In that thread, lescarphe said his PowerDVD codec display showed the same thing, as did saginawjuggalo and FoxyMulder with their PS3s. Shortly afterwards, Coxwell reported the same thing in the PQ Tier thread. Meanwhile other users thought these guys were insane as their own displays showed they were watching AVC encodes. 
As I now have lgans316's MPEG-2 disc in my Blu-ray drive I can confirm without a doubt that this disc contains an actual MPEG-2 encode different from the AVC encode on other pressings. As proof, here are the massive specs listings for each version. (note that the audio is actually 6.1 discrete channels, but encoded as 7.1 LPCM)
AVC version (specs courtesy of Phloyd using BDInfo v0.3.1):
MPEG-2 version (specs using BDInfo v0.4.1):
Differences:
Disc size: AVC: 48,362,529,368 bytes | MPEG-2: 48,424,650,234 bytes
Unrated movie size: AVC: 23,020,302,336 bytes | MPEG-2: 22,999,492,608 bytes
Unrated total/video bitrates: AVC: 30.74/21.56 Mbps | MPEG-2: 30.71/21.53 Mbps
Rated movie size: AVC: 22,579,138,560 bytes | MPEG-2: 22,576,723,968 bytes
The Rated versions' bitrates happen to be practically identical, but are actually different at kbps precision. And of course, the PiP encode stats are identical on both versions (which proves they are being measured the same way).
In case anyone's still thinking this is a "flagging" issue on the MPEG-2 disc regardless of the number differences, the video is definitely decoded by MPEG-2 filters on a PC. AVC filters refuse to accept the output of Haali's video splitter for these files.
For the MPEG-2 version, "modified" dates range from 11/18/2006 to 01/08/2007, with some dates in between. The PiP was modified 11/18/2006. The 3 seamlessly branched files were modified 01/08/2007.
MPEG-2/Unrated graphs (Rated version is basically the same):
MPEG-2/PiP graphs:
Can anyone with the AVC version and a BD drive please post the "modified" dates/graphs? How about a PIX comparison? MPEG-2 vs AVC: same studio, same master, same bitrate. Could be interesting. I noticed some pulsating in static shots on the MPEG-2, possibly blocking elsewhere. I wonder if this is alleviated in the AVC.
Conclusions:
- PS3 and PowerDVD always display the codecs correctly, regardless of firmware
- Lionsgate encoded, authored, and pressed one version of this disc (probably MPEG-2) and then for some reason decided to re-encode and replace just the main movie, re-authoring and re-pressing with the rest of the disc structure kept seemingly identical
- The unannounced MPEG-2 version somehow made its way into retailers' stock, including Amazon and Movietyme
There is also a July 2007 High Def Digest forum post claiming the same thing of Lionsgate's Young Guns release.
Is it possible to tell which version you have from the disc or package markings? I don't think the other thread quite nailed that down.

The Rated versions' bitrates happen to be practically identical, but are actually different at kbps precision. And of course, the PiP encode stats are identical on both versions (which proves they are being measured the same way).
In case anyone's still thinking this is a "flagging" issue on the MPEG-2 disc regardless of the number differences, the video is definitely decoded by MPEG-2 filters on a PC. AVC filters refuse to accept the output of Haali's video splitter for these files.
For the MPEG-2 version, "modified" dates range from 11/18/2006 to 01/08/2007, with some dates in between. The PiP was modified 11/18/2006. The 3 seamlessly branched files were modified 01/08/2007.
MPEG-2/Unrated graphs (Rated version is basically the same):
MPEG-2/PiP graphs:
Can anyone with the AVC version and a BD drive please post the "modified" dates/graphs? How about a PIX comparison? MPEG-2 vs AVC: same studio, same master, same bitrate. Could be interesting. I noticed some pulsating in static shots on the MPEG-2, possibly blocking elsewhere. I wonder if this is alleviated in the AVC.
Conclusions:
- PS3 and PowerDVD always display the codecs correctly, regardless of firmware
- Lionsgate encoded, authored, and pressed one version of this disc (probably MPEG-2) and then for some reason decided to re-encode and replace just the main movie, re-authoring and re-pressing with the rest of the disc structure kept seemingly identical
- The unannounced MPEG-2 version somehow made its way into retailers' stock, including Amazon and Movietyme
There is also a July 2007 High Def Digest forum post claiming the same thing of Lionsgate's Young Guns release.
Is it possible to tell which version you have from the disc or package markings? I don't think the other thread quite nailed that down.
I just got a new copy from Amazon last month and it was MPEG2.
