I have some foreign language films that I'd like to rip to single .avi or .mpg files for each film however I'd like to have the option of choosing the subtitles when viewing the new files (when I feel like reading them). With 'Handbrake' I can only 'burn' the subtitles over the movie, whereby they are permanently displayed when viewing the movie. On a DVD you have the option of displaying subtitles. They are always selectable at any stage in the film from the main menu. I'd like to make an single .avi file with a similar option. Is this possible?
