i did some homebrew home work on the net and found a cool player called pmplayer for the psp. after using it i found out it needs .pmp files for playback. also there is a option to turn on- off the subs. how do i make a pmp file (i am fluent in encoding, but there is no info on the net about this container) and what sub format does it take? do i need to mux it into the pmp file or use external .srt,etc subs? ANY help would be great

thanks
