Do you rip to a directory structure, an ISO or do you create an MKV (presumably uncompressed) of the movie? As I get closer to getting a NAS I need to think about how i'm going to do it so your thoughts are appreciated. So if someone stumbles across this and doesn't feel like reading it all here's a summary: Most rip to another format (e.g. MKV) If you're going to transcode on the fly you probably do not want to recompress/transcode the audio/video MakeMKV is recommended to remove extra audio streams/subtitles that you don't want and then converts the m2TS file to an MKV If you want to reduce the size of the movie, several here use Handbrake and defaultluser's post may help (I haven't tried that yet and I may not, given the amount of storage I have available. mvmiller12 has an alternate method of reducing file sizes that uses EAC3TO to either compress or remove audio streams MeGUI x264 to re-encode the videos to smaller bitrates (he uses x264 because most devices can h/w decode it, including a firestick, while x265 has less support. There is further advice within his post.
