Hi,
I run a video to DVD conversion website and use Pinnacle Studio 9.1 for captur/edit/render I also have Adobe Premier Pro 7.0 which is expensive and time consuming to use. I decided to increase my oprions and bought Ulead VideoStudeo 7 and have just upgraded to version 8. So far I am reasonably impressed but need help and am very disappointed that this item isn't mentioned in the instruction manual which came with the software.
If I capture from VHS video using DV format the end result isn't to bad. When I follow the tutorial instructions and set format to DVD or MPEG to ensure an MPEG format to render and burn to DVD the problem starts. At intervals during the capture process a popup appears which says DV Transcoding - Flushing DV Transcode Buffer, during this process capture stops and restarts on completion leaving a gap/jump in my captured footage. Does anybody know what this means and how to stop it ruining my MPEG captures. My capture device is a Pinnacle Moviebox DV external with firewire connection. I have used every setting possible in Win Xp and Video Studio to stop this with no success.
Just another little thing when I boot up VideoStudio it won't pick up my capture device until I've booted up Pinnacle Studio 9.1 once then it picks it up OK.

Horsepower...
Your computer should be optimized for video editing, and you need adequate horsepower to do realtime mpeg encoding using software.
What's happening is the video is going into your computer via firewire, but it is being buffered, and your computer is transcoding it to mpeg on-the-fly. The problem is when that buffer fills up, it stops capturing to "flush" the buffer (finish transcoding the dv video that's already in the buffer). When it's done flushing the buffer, it starts up again with the dv capture.
This works fine when you are dealing with a digital camcorder, because when the capture stops, the digital camcorder also pauses -- so you don't get any "gaps" in your finished video.
But this does not work when you are using an analog-to-dv converter because when the capture stops, there's no way to pause the analog video source -- so the video source keeps on playing even though the dv capture process has momentarily stopped while the flushing of the buffer occurs.
What are your computer specs? processor speed, memory, OS, etc...
Try stopping ALL non-essential background tasks that might steal cpu cycles away from your captures (virus scanner, task scheduler, screen saver, spy-detection, etc...).

Thanks George,
I have tried everything switched off and my internet connection disabled. My PC spec is as follows.
CPU = P4 2.6
Ram = 512MB.
Graphics = 128MB ATI Excaliber RADEON 9200.
OS = Win XP Pro with service Pack 2
From what you say I'm not sure another 512MB ram would make much difference, maybe I'll have to keep capturing AVI, though it seems rendering MPEG is quicker. I have noticed sometimes for some reason MPEG capture is OK and doesn't flush the buffer, not sure why. I'd prefer to crack VideoStudio rather than return to Pinnacle Studio 9.1 which is painfully slow at rendering.

Your Pinnacle Moviebox DV is supposed to have an internal processor that is doing the analog to digital conversion and the encoding of the video stream. Therefore, your computer CPU may not be as busy as you think. Try monitoring the CPU busy % with the task manager.
On the other hand, the capture box may be relying on some special Pinnacle capture software to complete the conversion - something that Video Studio may not be doing "properly." When capturing analog with a special box, I prefer to use whatever software came with the box just to avoid this kind of problem.
My advice is to use the Pinnacle capture software to capture to Mpeg2 and then edit with Video Studio. IMHO, there is NO advantage to using Video Studio to capture.
BTW, make sure that you install the Burning Engine Patch and the 8.01 Update because there is a memory leak bug in 8.00.
