I dismissed it during the viewing (although it was very distracting) and didn't think about it for a while.
More recently, I upgraded from a 360/add-on to a Toshiba HD-A20 and purchased Babel
on HD DVD, hoping the AVC/MPEG-4 encode would look better than the MPEG-2 on the Blu-ray version, but to my surprise it did not. I tried adjusting the black level on the A20, as well as connecting directly to the TV w/ both component and HDMI (I normally use 1080i/HDMI through my Yamaha HTR-6090 receiver), and adjusting the black corrector and gamma settings on the A2000. During this testing, I also started noticing subtler, but similar black/blue issues on titles such as V for Vendetta
and Lost in Translation
. The PLUGE on DVE looks totally normal.
I saw the same problems on my 360/add-on over component when connecting directly to the TV and through the receiver via 1080i component (the receiver can do an A/D conversion to take 1080i component and pass it through the HDMI output, so I wanted to eliminate that possibility).
Next I started testing on my PC w/ the 360 add-on drive and Cyberlink PowerDVD. I have a 23" 1920x1200 LCD that takes both component, VGA, and DVI inputs and I tested a variety of scenarios: PC via DVI, 360 via VGA, and 360 via component. All of the these tests revealed lots of detail that I had never seen before and there were no weird blue/black problems at all.
TL; DR -> The problem appears to be related to my A2000, as the issue manifests itself on both the A20 and the 360, regardless of analog/digital connection and whether or not the receiver is in the mix. Similar tests on a different display reveal no problems with the sources.
I have no idea how to proceed, but I would like to test the Blu-ray version of Babel
again, now that the 1.8x firmware has dropped and see if the issue still exists. Turning down the brightness removes the blue, but also masks non-trivial amounts of detail (treating the symptom, not the problem). Any suggestions would be very
