Ok, took a while to pull this together but here is a sample that 
demonstrates the issue:

ftp://tools:gettools@planets.shacknet.nu/sample.zip

Now, you'll need to have avisynth installed, and presumably some sort of 
h264 codec compatible with playing Blu-Ray discs through DirectShow. I 
believe installing PowerDVD 8 (free demo version) will give you that. 
There is a small batch file included that will let you see the same bit 
of video with either decoder. You should see some smearing halfway 
through the clip, and some macroblock errors near the end. This is a 30 
second clip extracted untouched from the menu background of the SUNSHINE 
blu-ray disc. The sample file is around 120 Mb.
