If it's from iTunes or Vudu etc. I imagine whomever got it then converted to lossless

But...that...is not how that works?

It sure is if you need to work on the video, like color etc.

Plus, AVC / H.264 in an iTunes file is not Blu-ray compatible - hence the issues DFNYC was having converting the Star Trek Into Darkness Enhanced Commentary.

You want to put something to play on a Blu-ray player, you need to convert it to a Blu-ray compatible video file. Same CODEC is not enough.
