adjacent captured clips do not play smoothly

I am a playful hobbyist in the UK capturing dv via a PCMCIA card plugged into a Dell Laptop onto a dedicated external firewire HD. Using the automatic scene detection function in the VV capture program, scenes are captured with an occassional dropped frame as files of proximately 250MB or less. This capture program works fine for obviously discontinuous footage (i.e separate files are created for separate pieces of footage). However, some of my footage that is obviously continuous (i.e there is no discernible change in scene or action) is captured as separate adjacent files. Under these circumstances, when I preview or play some of the 'middle segments' of these adjacent files there is a digital block like 'stutter' at the beginning of each middle segment lasting 1 frame(I think). Furthermore, when all of these these adjacents clips are placed together on the timeline (these clips are placed together without any fiddling of their position), there is a momentary but obvious stutter as one clip plays into the next. Unfortunately this problem occurs most of the time.
Incidentally I am capturing dv as avi using the default PAL settings i.e Lower field first and using default project settings. I do not think that the problem is connected with dropped frames because they seem to occur at different places/times. This makes me think that the problem lies either with the capture program itself or my laptops ability to capture files smoothly. This problem has frustrated my enjoyment of an otherwise wonderful VV experience. Any suggestions?

I forgot to mention that I am using VV3.0c

I had the exact same issue (NTSC). I found it best to avoid the automatic scene detection/file split scanario, capture it all in one *big* file, do manual splits, fades, etc. Then all plays smoothly.

I found no other way, nor seemingly did anyone else.

Thank you.

Hi FOlks,

I'm wondering what kind of camera was used...

Vegas uses the timestamp for scene detection, so there may be erroneous information on the tape.

If you can successfully capture entire tapes without these hitches, it might not be a laptop / HW issue.

You might try setting the minimum clip length in capture settings to exceed the points where the unwanted division occurs.

You could also use advanced capture to designate segments or even consider Scenalyzer for capture.

thanks for your advice so far, I am capturing from a Panasonic MX300(0)B dv camcorder. I will try capturing without using the automatic scene detection, and capture as big files. Hopefully this might eliminate the stutter in the captured files....just a shame that the automatic scene detection cannot be used. I will let you know if this helps.
