OK, besides this old ass thread
http://www.theisonews.com/forums/viewtopic.php?t=98961&highlight=mergeI couldn't find anything so here goes:
let's say I have a 720p or 1080p BD rip of a nice kiddie movie, but the audio is in english, and I want to strip it of the original audio and merge it with the spanish audio from a DVD or Avi, how can I do that? Is it possible to keep both languages and maybe switch streams?
