TV-Tuner/Capture Card similar to ATI AIW but has audio locked to video??

    I have been fighting the audio/video sync problem when capturing from
    TV using the ATI AIW card. It seems that the audio is sent out a rear
    audio plug, and that is plugged into the line input of sound card on
    your computer, and the sound is captured from the sound card while
    video is captured through the ATI AIW card. The audio and video
    always get out of sync after captures of any length. Apparently even
    their latest cards still do the same thing, according to the
    downloaded manuals from ATI site.

    Does anyone out there make a combo card like the ATI AIW with all it's
    features, but actually locks the audio to the video to eliminate the
    sync problem?

    Thanks,

    Jim

    You might try a different sound card as there can be a problem especially
    with onboard sound chips and sync problems.
    Even a cheap Sound Blaster card should work better then an onboard sound
    chip.
    just my 2 cents

    always get out of sync after captures of any length. Apparently even
    Incorrect. I used to use a AIW 128 Pro for years and never had any synch
    problems. I now use a 9600 Pro and still don't have any synch problems.
    As ub has said, synch problems are almost always related to the sound card
    and not the capture card. Run the PC Test function in MMC to check the clock
    accuracy of your sound card.

  4. Not sure about a combo card, but I got tired of that happening with my
    AIW card (not to mention out-of-control audio levels) and went to a
    Canopus ADVC-300. You can lock and unlock a/v as your needs or pgm
    source dictates, it has more features, and a proprietary stabilization
    codec, among other features.

    It was pricey but worth it for what I'm doing -no regrets! Maybe the
    150 model would work for you, but I don't know that it has the a/v lock
    feature.

    luck,

    Changing the sound card did the trick, the clock on sound card was off
    frequency.

    I have another problem with ATI AIW 128 Pro, did you have the problem
    that no matter what sound input you select when running the
    INITIALIZATION wizard (Line In is the default), when I close the TV
    application, and re-open it, the default has changed from LINE IN to
    AUX on the sound card, and if you don't go in an re-run the
    initialization wizard, you won't capture the sound portion. I seem to
    remember seeing a registry hack to fix this but can't remember where
    it was located in registry. Did you ever have that problem?"

    Thanks,

    Jim

    Hi David;

    Well, I already have an ADVC 100, but like the convenience of
    capturing some things directly into .mpg to save time.

    I also have an Osprey 200 card and the audio is locked directly to
    the video just like the Canopus, the video card itself has two audio
    inputs along with the video and it's locked together.

    Thanks fellows for helping me solve one of the capture problems.
