You can remux the audio and video streams with mencoder -of mpeg -mpegopts format=dvd:tsaf ... , then dump the vobsub information to get the palette values, dvdunauthor the subs and finally dvdauthor the final mpg + subs + palette with dvdauthor. Read the docs in dvdauthor to understand how to mux it all together. _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
