Just ran across a "hint" for doing forced subs using Handbrake. This is for those who do not want to add a forced subtitle track later using something like Subler, iFlicks, etc and are satisfied to have the forced subtitles burned into the video so that you do not have to turn them "on" in the aTV subtitle menu. On the subtitle tab in Handbrake, for Track, select Foreign Audio Search. When you select it, Forced Only and Burned In will be checked. If forced subtitles are detected, they will be burned in (no turning on in aTV menu). If there are no forced subtitles, nothing occurs. I just tried this with "Salt" and it worked perfectly.
