Forgive me, John, for my bad English.
Got authoring DVD and Bluray in DVDA 5.2 with Dolby AC-3 5.1 as follows:
1º) I was render in Vegas Pro 11 only video (no audio) in MPEG2, full HD (1920 x 1080)and saved inner folder the files (file’s_name.m2v, file’s_name.m2v.sfl and file’s_name.m2v.sfvx).
2º) After that, I was render only audio in Dolby Digital AC-3 Pro (5.1 surround DVD option) and saved in the same folder with the same name (very very important) the files (file’s_name.ac3; file’s_name.ac3.sfk and file’s_name.ac3.sfl).
3º) Then, wonrking at DVDA 5.2, when the video file is inserted, audio is automatically inserted, and… “voilà ”. Perfect 5.1 surround sound media. Any questions send me e-mail pausa@terra.com.br.
