    I converted an avi file using TMPGEnc and it created 2 files. An m2v video file and a wav audio file. I then went into ifoedit and set the m2v file as the video source and the wav file as the audio. When it was finally done there was no audio. What did I do wrong?

    I went back and checked the wav file, opening with windows media player its 40 minutes of silence. Whats the deal?

    Please does anyone know what the hell is wrong with this? I used another program to extract the audio to ac3 format and it played fine, i did the same thing with ifoedit and still no god damn audio. Please I have to have this dvd in a half an hour.

    Well I had to use dvdsanta which resulted in many freezes and off-synch audio for many parts of the dvd. You guys really helped!

    It could be that that AVI had AC3 sound (which TMPGenc cannot decode at all and, therefore produced only silence).
    Did you notice the 'audio input' line, on the main screen, reaining emply?

    Whan I make AVI --> DVD I use only this method (so-called 'using elementary streams'):
    - with TMPGenc I make AVI --> M2V (actually, I also unlocked the tepmlate so instead of doing M2V+WAV it produces only an ES (video only) stream, instead of System (video+audio) (M2V+WAV) but you can do the usual way and throw away later the WAV stream;
    - with VirtualDubMod I load the AVI. I do Stream__Stream List and see which kind of stream it is.
    1.1) If it shows 'MPEG-1 Layer 3 (MP3)' that AVI had a MP3 stream and I press 'Save WAV'. Please note: the that WAV stream must be large 10.1 MB per minute. If not, it means that stream is somewhat damaged (dor instance, a MPEG with 48 kHz audio instead of a 44.1 kHz). In this case, try to decompress the stream by loading it with the standard VirtualDub (or VirtualDub-MPEG2, if the file is a MPEG-2 instead of an AVI or a MPEG-1), setting Audio___Full processing mode and doing File__Save WAV.
    1.2) Encode the WAV into AC3 192 kbps 48000 Hz using FFMPEG GUI.
    2) If it shows 'Dolby AC3' that AVI had a 48000 Hz Dolby Surround audio stream and I simply press [demux].
    3) author with IFOedit the DVD.

    This is what I called 'authoring a DVD using elementary streams' in my 'sticky' thread (which must be written badly, since no one reads it) http://forums.afterdawn.com/thread_view.cfm/351013

    Just a suggestion: since you cannot move like on DVDs, neither moving by chapter or selecting a certaing beginning point, make a file named 'celltimes.txt' made like this:

    7500
    15000
    ....
    for a PAL movie, and

    8991
    17982
    .....
    for a NTSC movie.

    Then, in IFOEdit, load it under 'scene changes/chapters'.
    In this way, pressing NEXT on your DVD player will let you skip 5 minutes.

    Please note:
    5 min * 60 sec/min * 25 fps = 7500 frames (PAL) or
    5 min * 60 sec/min * 29,97 fps = 8991 frames (NTSC)

    I made my [bold]celltimes.txt[/bold] file with Excel, then copying and paste into a txt file. I put three hours (180' = 10800" = 270,000 frames) for my PAL celltimes.txt movie, so it it valid for any movie.
    Anyway, should L_movie be < 270,000 frames (3 hours) IFOEdit would give me no error.
