Does anybody know how to do this? I've found a few guides from googling but using those guides I was not able to preserve the sound of the movies that I have. I ask this question because I have the Philips DVP642 (plays divx avis right off CD's/DVD's) and it does not support sub + idx files, so if I can somehow re-encode my videos to permanently attach the subtitles, I could just burn all my Asian movies with subtitles and watch them on my DVD player. Any help appreciated!
