Thanks for the info, CatBus!

I certainly want the highest possible bitrate when I watch these. I haven't seen the originals since they were each released and am probably more excited than a normal person should be. I was 11 in 1977 and I think Star Wars may have mutated my brain.

I'm going to pipe them into my home theater system. I have burned blurays from the AVCHD versions and they look pretty good, but if the difference is noticeable I will figure out how to watch the MKV versions.

How do you watch them yourself? Directly from some kind of media streamer or do you burn blurays? Can the MKVs be made into blurays without quality loss?
