Hello. Trying to rip my Blu-ray movies into iTunes. Using MakeMKV for the actual rip, then Handbrake to transcode into m4v/mp4. Problem: the file HB producesafter six or seven hours, and which is basically the same size as the input MKVis unreadable by QuickTime. Says it's in an unplayable format. Changing the file extension from m4v to mp4 doesn't help. I'm sure I'm doing something simple and stupid wrong, and would appreciate any pointers as to what it might be. Thanks!
