getting subs on my film.. using BSplayer

was wondering if anyone could tell me how I get sybs on my film..

I am using Bsplayer and yeasterday used subs on one of my films. HERO. With that film I could just load the subs with Bsplayer as the subs was .srt.. but now I wanted to display subs on my 8mile.. but here its not .srt but .sub, so I cant get them displayed.. (I know the subs and film have to be in the same folder) please help..

read a bit here in the Forum and know think I have to use vobsub, which I have downloaded then.. but is this right and if it is how do I use it??

thanx:)
