So, I ripped a Blu Ray using MKV, then converted it using handbrake...I'm trying to add meta data, but when I navigate to open the file, it's grayed out. What am I doing wrong? File type = [name]_mkv Do I need to convert to mp4 before exporting to iTunes? UPDATE: I still can't get MetaZ (or anything for that matter) to open up the MV4 that I created via handbrake... "The file 'Step_Brothers_Disc_1_t01.m4v' is in an unsupported format." The image of the file is a white sheet with a folded upper right tab. " I converted to M4V on handbrake using "Normal" settings. My goal is to import into iTunes and stream via Apple TV3. A solution would be very welcome! Frustration is starting to mount.
