    Default Audio gets lost

    I have an avi file which plays fine. Converted same to a SVCD and the resulting mpg file had no audio. Had that happen before. Used VirtualDub to extract the audio and then with the avi and resulting wav file used TMPGenc Plus to create a new SVCD mpg2 file. Still no audio. Any ideas. Thank you.

    Yes the wav file has sound. I got to thinking maybe a mpg2 has sound and a SVCD mpg2 does not. Dunno...might use an RW and see if I get sound. The mpg2 file created has a size but not a length.

    Where is this environmental settings?
    OPTION/Environmental Setting/VFAPI Plugin. Now Right click on Directshow Multimedia File Reader Set it to higher priority until it is the highest of all(usually +2).

    When you saved the wav, did you have audio on full processing? Because TMPGEnc should have no problems converting pcm wav even with default VFAPI settings. If you have audio set to direct streaming, then you just get an mp3 with a wav header and it is basically the same as leaving the audio in the avi.

    that's very true. i should have asked your steps creating the wav in vdub. in the link i gave shows creating a wav file that will work np in tmpgenc.

    also very true, that's why i thought it a longshot. i think celtic you have it, must be the way the wav was created.

    it would be nice to see the file info or at least know what the original audio is AC3 or whatever. the method in that link can be used with vdub, OR demux with vdubmod and convert to wav with besweet or px3's--many ways.

    I had an older version of VDub....extracting the wav file and using with TmpG worked fine. Thanks.
