Be sure and turn off "Use windows sound system" in FF and in Premiere advanced properties for the Fast DV under "audio" tab. You may have to recapture the video if this was turned on.

You must turn off the windows sound and let the sound be captured by the DVnowAV card. This should always keep your sound in sync. Also in your editing, monitor the sound through the card also using an external monitor or TV if possible (in Premiere).

I have had trouble with audio sync as well. Regardless of the settings used during capture and/or editing, the audio goes out of sync when playing back from the timeline premiere to analog out. It's a funny thing, the audio doesn't lag consistently by a few frames, but gets further out of sync the longer you play back. Even if you calculate the entire timeline as film and play it back in Fast.forward it does the same thing with analog out. The only thing that solves this is using the "print to video" feature in Premiere. For some reason the audio is handled differently and stays in sync.

"You must turn off the windows sound and let the sound be captured by the DVnowAV card. This should always keep your sound in sync. Also in your editing, monitor the sound through the card also using an external monitor or TV if possible (in Premiere)."

I've been trying this, but I can't hear the sound in FF, Premiere or the clips I export from Premiere (QT,.wmv, etc...).

I have my vid out and audio out going from my Hi8 cam into the breakbox. However, unless I plug the audio out into my soundcard, I get no audio. I tried disconnecting the audio out from the breakbox to my sound card, trying to put the auido through the cable, but no go. I don't have a TV to set up, besides, that wouldn't effect my outputted movie sound, either.

Any ideas on how to try to set this up? In other words, the only way I get audio is from the audio out on the BB going to my sound card with "Use Windows Sound System" checked.

Thanks for your help,
Valerie

I've been fighting this sync problem off and on for months now. "Windows sound" off, "windows sound" on, defrag the video drive, etc., etc. Clips are always in sync when played individually from FF, and when played a few clips at a time from Premiere. In Premiere, I've just played from the timeline, or used "Print to Video". (The option to "Export to tape" is grayed out for me.)
Ususlly, what happens is that I have sync until somewhere after 8-9 minutes of a 14 minute program, then I start seeing desync. Sometimes A leads V, and sometimes V leads A. Desync can happen anywhere up to the last half-minute or so of the program, and, occasionally, the program stays in sync 'til the end. It seems to me that this means that the capture with FF was OK, and the desync happens on playback in P6. In one case, the sound was suddenly out of sync by a few seconds, lagging behind the video. I happened to be outputting to VHS tape at the time, and when I played the tape back, I found that an entire 5-second video clip was missing, although its audio was on the tape, but mated with later video (!!) which threw the sync badly off.
At present, I'm running on a 450MHz PIII with 256MB RAM and a 60GB IDE video disk.

This could be a problem with your source tape. If you are capturing off of a poor quality VHS tape it's control track may have gotten out of sync. The video will look fine on TV until you try to capture it. Most decent quality VHS tapes will be fine. To fix minor control sync tracks I use the Sima Color Corrector Pro (round $100 from www.videoguys.com ) and it's helped all but the lowest quality tapes. You may also try copying the source over to another VHS tape. You'll lose a bit of quality, but the new tape may provide a new sync track.
If the source tape has dropouts (fuzz) this may also happen.

Hi JVID,
I have same problem as you. I found only way. Exporting the clips as a file and Print to tape in FF. There are no synch problems. Let me know what´s your solution.

Regards

Lukas
