Hello all.. this is a follow up question now for my OGM to DVD conversion that I am pondering to make - after I get an answer to this and my DVDs are done, Ill be sure to make a guide so that ppl dont run into the same problems I have. so here is the question, after demuxing my .ogm file I now have 1 AVI and 2 OGG files (stream 1 and 2). Since I am trying to make a very decent (if not good) DVD -> OGM -> DVD conversion, I need to get those two OGG streams into some other format that TMPGEnc DVD Author can understand (*i.e. .mpg, .m2p, .mpa, mp2, ac3, wav, abs), and I thought AC3 surround would be a good choice (please let me know if otherwise). Does anyone know how I can create an AC3 audio file from 2 OGG vorbis files? THank you in advance again. Edit: I found a software called [bold]lamedropXPd[/bold] which transcodes from OGG to MP3 but now i have to figure out how to get those two MP3 Streams into one AC3 file. !
