Cycle Audiostream
 

Not sure if this is a bug or not, but Cycle Audio Stream doesn't work (on mkv files atleast) It doesn't cycle simply enough.

It works well for me with an avi (divx 5) file. I don't have an mkv to test... sorry.

Cycle audio stream (Shift-S) works. Tested BSPlayer v1.36 + MatroskaSplitter v1.0.2.9 + AC3Filter v1.01a RC5 + ffdshow 2006-08-03 and two audio streams.

But... You need to execute the Cycle command several times.
0. Default audio stream plays.
1. Invoke Shift-S. First audio stream (the same) is selected. (Maybe the player thinks it has advanced to the next stream already.)
2. Invoke Shift-S. First audio stream continues to be selected.
3. Invoke Shift-S. Player chooses the other audio stream.
4. Normal Cycling from now on.

I think it's not worth to pay much attention to this bug (?). It also takes two presings of the spacebar to start playing the movie.

The reason was mostly for making it possible to make a script for salling clicker
