In Handbrake I added subtitles to my m4v's and I noticed that in playing [some] movies either in iTunes or otherwise the subtitles cannot be turned off. Settings I used in HB: Track: English - (Bitmap) (VOBSUB) w/ Burned In I didn't select burned in at first as I thought it meant you could not turn them off until I read it simply meant the same format as the DVD. UPDATE: Only a few movies have this issue. "Dark Water" is one, but playing others in VLC or in XBMC I can disable/enable the tracks. What did I do wrong and is there anything I can do? Thanks guys, I know I posted a lot of questions as of late, and I'm sorry, but you've all been so amazingly helping!
