  1. I currently own a Creative Digital VCR capture card. It has a TV tuner and S-Video input, so I plug in my camcorder and record home videos. The MPEG2 files that the Creative Digital VCR creates are standard MPEG2 videos with VBR and MPEG 2.0 audio at 32KHz and 384kbps bitrate. I am trying to convert to MPEG1 at 1600 bps video and 44 KHz audio. I have tried loading into FlaskMPEG and converting, but the video that results is one that does a stop and go thing at 1 second interviews.

    I then tried using DVD2AVI to save the video as a project (.d2v) and as an mpeg audio stream (.mpa). In order to convert the 32KHz stream to 44KHz, I open the .mpa file in Winamp, select DiskWriter as the output, and I get a resultant 44KHz wave file with excellent conversion. I then load the .d2v file and the .wav audio file in TMPGenc and start encoding to MPEG1. However, the resultant video is most of the time off-sync with the audio and the video is choppy, as if the video were at 20FPS.

    The reason I do not simply load the .mpa into TMPGenc is that I have found TMPGenc does a poor sampling rate conversion from 32KHz to 44KHz. The resulting sound has a mechanical overtone to it.

    Has anyone had successful usage with the Creative Digital VCR card and/or know software that will convert MPEG2 with 32KHz sound successfully to 44KHz? Or what am I doing wrong??

    Thank you very much!!

    Sir;
    I think I know what your problem might be. You seem to be trying to use TMPGEnc to multiplex the .mp2 audio and .m2v video. TMPGEnc is a superb MPEG encoder, but it ain't a great multiplexer. That's probably why you're getting sync problems.
    Try this:
    [1] Split out the audio from your .AVI file using MPGEnc and save it as a 32 kHz .WAV file.
    [2] Sample-rate convert the 32 kHz .WAV file to 44.1 kHz using Winamp (or any other app -- I use Sound Forge, but to each his own).
    Save it.
    [3] Encode the 44.1 khz .WAV file at 224 kbits/sec (VCD standard)
    using some application like Toolame and save it as an .MP2 file.
    [4] Use TMPGEnc to encode your .AVI file as an MPEG-1 file at 1600 kbits (WARNING: the VCD standard is 1150, so some DVD players won't
    play a VCD encoded at 1600 kbits/sec.)
    [5] Use BBMPEG to multiplex the encoded .M2V video and .MP2 layer-II audio file into an integrated MPEG-1 file.
    BBMPEG is THE best multiplexer/de-mulitplexer, bar none. It's the gold standard. Any time you need to do some operation with audio only, you should *always* multiplex using BBMPEG. (Also known as AVI2MPG2)
