    Well this one had me spinning: Picture transferred from DVD fine. But I tried to redo it several times not noticing that the audio was Pulse Code Modulation. The transfer to an avi file has no sound. Is it simply a matter of using the right player?

    I use VLC which is supposed to do it all.

    Any help on this audio problem?

    I think DVDFab has option to encode to other formats


    @loninappleton - what does mediainfo or gspot say about the audio in the AVI ? Is it actually present ?

    speakers on mute ?

    can't say i ever came across a video in an avi container with pcm, maybe not an acceptable audio format.

    I know you have before

    It's just uncompressed audio, with byte order swapped compared to LPCM

    It depends on the edition that DVDFab has come out. MKV is now offered in the newer one. But if PCM is raw audio can the prog even see it? I even swapped around the 5:1 dts audio in place of stereo-- still no go.

    I will run the file through GSpot as you suggest.

    Will follow up tomorrow. Since the sound on this is important, I'd rather not have to go through trying to tease it out which I'm no good at anyway.

    From GSpot (I don't know how to transfer the whole report)


    File is listed as Multipart Open DML AVI 2 Parts

    Audio Codec PCM audio
    48000Hz 384 kb/s tot (2 chnls)

    Looks odd.
    Uncompressed 2-chan 16-bit LPCM audio at 48kHz would be 1536kb/s.
    So either you have some sort of compression or you have only 4 bits per sample.
