[HELP] .sub files

I downloaded a clip, and there's a .sub file which I think is for subtitle.
How can I use it?
Can I burn it together with the clip in a VCD?

Thanks in advance.

PS; Ive searched, but found only ways for DVD or Mac

I believe you can't use an "optional subtitle" for VCD.

Ok, then how do I used it??
