[QUOTE=mknoblock;50278]thanks; I'll get DVDSubEdit and continue to pursue this. I assume this is not a straightforward process? For example, if I have a French film that has English and Spanish subtitle tracks, and select only the English subtitle, when decoding to MAIN MOVIE, the subtitles do not appear, whether played on a burned DVD or in a player (PowerDVD). I can copy/burn the full disk, of course, but then you lose the beauty of the Main Movie feature.[/QUOTE]No, this should be very straightforward, but there are a few caveats: When using Main Movie (or Merge or Customize), if you want the subs to play unconditionally and without player intervention (as AGJ suggested) you must select them as default (turn on the default arrow) and you must play the output files as a DVD, i.e. if you try playing only the VOB files, they will not appear, since the default play coding is in the IFO file. This works correctly with most standalone and software players. If all else fails, DVDSubEdit has the ability to turn any of the subs, even the entire stream, into true forced subs almost instantly. Also, any player controls that would jump to the movie feature should be turned off (e.g. VLC).
As an exercise once, I took a R1 DVD (English) and made it play back with French audio and Spanish subtitles using the default arrow.
//EDIT//
If you are using PowerDVD or WinDVD, try playing the movie by double clicking on the VIDEO_TS.IFO file (or "Open With..." from the file context menu if these files are not associated with the player app).
