When ripping (legally owned) Blu-Rays with a product like MakeMkv, I'm essentially making an easier to use backup of the entire movie. This means I end up with MKV with a lot of subtitle tracks, but in many cases none of them are default or forced subtitles.

VLC correctly plays these files (i.e. leaves all subtitles turned off) but Totem doesn't - it defaults to picking an English subtitle, and in "Auto" mode still insists on displaying *something*.

Since MKV at least is very specific and clear about how tracks in the container should be handled, Totem should respect this - picking a track only if it's the default, not just because it's there.
