Freezes and no audio

[Zellus]

I've recently had problems with bsplayer freezing when I click on the open button, when I pause and when I puch the stop button.

Also I just got Slayers(an anime) and I started whatching it only to realize that I had no sound at all. Now the file plays sound in media player classic but is really patchy(video wise), bsplayer plays the file smoothly but no sound(see my prob).

According to the name of the file it uses the audio codec "Tad Dual Audio".
Oh yeah if it helps any the files extension was ".ogm"
BTW: what does the "bs" in bs player stand for? :?
