Jitters on capture

I was putting some 3 minute clips on the timeline & after rendering & burning to DVD, I noticed jitters only on a couple of clips. This didn't happen back when I was using Windows 2000. Is there some sort of problem in Vegas capture that would cause this occassionally? If I delete the problem clip & recapture this usually corrects the problem but at this point I wasted a DVD & 5 hours of render time. I thought at first it was the encoder/ or bit rate but I ruled that out by rendering the timeline again at a lower rate with the same problems. It almost appears that the canopus ADVC-100 is doubling a frame at times. I have a pent 4 with 512 ram, no conflicts and a SIIG firewire card. Canopus said try unlocking the video & audio switch on the box but that didn't help. I'm confused about the cause because I did a clean install of XP Pro & switched to the canopus from Hollywood dv bridge around the same time. Also this happens when the program source is from a DVD, so it's not only with VHS tape.

This never happened in Win2k?

Does Video Capture tell you that frames were dropped during capture?

So you switched from 2000 to XP and from Hollywood DV bridge to Canopus at the same time. You didn't have the jitters when you were on 2000 with the Hollywood DV Bridge? Or did you change to the Canopus while you were using 2000?

Never had the jitters on Windows 2000 w/ Hollywood DV Bridge. It never said frames were dropped on the video capture. Is XP just as good with video editing? Should I have enable capture device checked? What should be checked with the canopus ADVC-100?

You probably also updated to 3.0a. This device functions in a similar manner to the Dazzle in that it stuffs timecode in the stream. If the device doesn't properly stuff the timecode for every frame, Video Capture may pick this up as phantom dropped frames and when loaded into Vegas insert extra frames and hence the jitter or repeated frames.

I've posted a 10 step work around to get the Dazzle to stop updating the timecode in the DV stream, however no such thing exists for the Canopus converter. You may ping Canopus and see if they have updated firmware that doesn't do this.

Neither the Sony DVMC-DA2 nor the PowerR converters exhibit this.

So is this why this never occured in premiere. Is this a Vegas capture issue & should I capture in Premiere & do all the editing & rendering in Vegas until Canopus comes up with a solution?? Thanks.
