I would like to see a switch for displaying only forced subtitles. DVDFAB has this option.
I don't want subtitles on all the time (in English), only when a non-English subtitle appears on the screen.
An example would be when Jabba the Hutt is talking in Return of the Jedi. Because I understand Luke Skywalker, I don't want subtitles when he is talking; But when Jabba is talking I need IdealDVDcopy to be my C-3PO.
