How to support subtitles in 8player

hi hi, i just bought seagate's flexgo home NAS, and i had tried a few apps to stream videos to my iphone, all of them dissapointed me as either the video is out of sync with audio or the files just won't play, until i bumped into 8player. Everything is just perfect, except that i can't see my subtitles (actually this occurs to alot of other apps except buzz player, but streaming via buzz player slow as hell)...I am using the lite version and srt files as my subtitles, it will be great if anyone can show me how 8player can support subtitles, thanks.
