Opening the avs for the BD raw using both DGSource and AVCSource output correct video in VirtualDub.
Switching to .mkv container for 1080p x264-encoded 8bit source; I am now using
FFVideoSource vs. DGSource, using stacked 16bit output with f3kdb.
Here's example DGSource output:

When I encode to x264 and specify input depth as "16", FFVideoSource will output properly but DGSource leaves me with a video that appears exactly as the frame in the picture.
