Hello everyone,
MakeMKV does not recognize/map a few obsolete language codes used by some older DVDs.
For example, 'iw' (old code for Hebrew) is not mapped to the ISO-639-2 (3-char) code
when creating the .mkv file.
There are three of those codes i'm aware of:
old -> new -> 3-char:
"in" -> "id" -> "ind" (Indonesian)
"iw" -> "he" -> "heb" (Hebrew)
"ji" -> "yi" -> "yid" (Yiddish)
Cheers..
