I own a collection of Blu-ray discs that I recetly purchased (Battlestar Galactica - The Complete Series), and I ripped the individule episodes with subs and chapters to MKV files. All broken down by disc#/season#/episode# and named accordingly. Each file is about 17GB and there are nearly 40 files. The whole set occupies nearly 700GB. I don't really want to uses that much space on my media center drive. Right now I have it all stored on a 1TB USB drive but now that drive is useless for anything else. I've got a couple of cheap 500GB USB drives, and I don't mind dedicating one of them for playback when connected to my media box (WDTV Live). What I want to do is compress the files using handbrake without losing a lot of quality. Can someone recommend a startling point with the settings, or should I just select a particular preset profile? Which one? I also have considered joining all the episodes of each season into one file using MKVToolNix but that seems to crap out and produce errors. The App. notifies me of the errors but I can't for the life of me figure out how to read the error log and see what they are. Any advice on this little project would be appreciated. I don't need original quality, but I'd like to stay as close as possible. I've asked for help at Video Help website but I'm not getting anything much there. That site is generally kind of down on people using Mac.
