I thought that too so I double checked, but I do a straight lossless rip using MakeMKV; the only thing MakeMKV does is creat the mkv container. That said: blurays don't have consistent codecs, so it makes me wonder if if I should be matching that as well. Until now, I was using H.264 as the basic standard when re-encoding.

This is one of those times I could really benefit from an expert breaking down for me all about video.
