Maybe you can split it up into two configurations. One simple, where you enter the languages you understand in the order of priority, i.e. for you "eng ger" and then it chooses "eng(audio),eng forced(sub);eng(audio),off(sub);ger(audio),ger forced(sub);ger(audio),off(sub)" (hope this pseudo code is readable). Maybe forced should not only account for "forced" flag, but also the string "forced" in the subtitle description?
Then a second advanced feature like the one used in Haali or rather more advanced like you proposed some pages back (
http://forum.doom9.org/showthread.ph...52#post1519452).
Most users will choose the simple logic, just stating that they only speak english and/or another language and the few others that need more individualization can choose the advanced logic. I guess everyone should be happy then?
