Play MP3 as second audio stream / Frame by frame
 

It would be great to play an MP3 file during a movie, for example a separately recorded commentary track.

Plus, I'd like to have the option of skipping frame by frame through a movie (I haven't found that yet, maybe I haven't looked good enough)

u can pause the playback and hit "left" and "right" cursor to jump to or previous or next frame

OOPS!!! :oops: Sorry about that, but my first request still stands!

not really :P , you can load a separate sound file by hitting shift+L (default key).
To help localize it, I'll say this also appears in the same pop-up menu than "exit" and "about" commands.

However, I don't think you can do what you want with that soundtrack (like cycling it), as bsplayer will synchronize it automatically.
But for a commentary track, that's perfect ;)
