I have tried to capture, and can, but a window comes up saying" Flushing DV Transcode Buffer: then there are what looks like a count down of the ?? Buffer???

Yes, I am new, and will take ALL the HELP I can get.

SEARCHING is your friend.

To sum things up, you are trying to capture in MPEG2 format, and your system isn't capable of performing the transcoding in realtime, filling up the buffer. So UVS is forced to stop the capture, finish the transcoding of the buffered data, and then resume.

... and further to what Torsten has already said, this teaches the lesson that with your computer at least, it is probably much better to capture DV format (rather than MPEG), then do your editing, and only then create a DVD-compatible MPEG (Share > Create Video File > DVD).

Again thanks, but if you could take me through it a step at a time, I might be able to do what I need to!!! They(ULead) that I had to run in the mpeg2, out put to vds, and **---- Help again

To sum it up quickly: DV format is (essentially but not quite) uncompressed video. Capturing to DV format just invloves a simple transfer of data from camera to hard drive - very little work for the computer to do.
What you find on a DVD is video in mpeg2 format - this is significantly compressed video. The question is - at what stage of the whole process do you want to do this conversion process? You are obviously doing it at the capture stage (OK, many people do this), but converting DV to mpeg2 "on the fly", or in real time, is incredibly demanding on the computer. It periodically has to say "hang on a minute, give me a chance to catch up".
I prefer to capture in DV format anyway - I think it's better for editing. I suggest you do that, do all your editing, and then let the computer chug away for hours transcoding the project into mpeg format.

Jimw,
There is a step-by-step recommended procedure posted in the sticky at the top of this forum. I suggest that you start there. It outlines the two different capture methods (AVI & Mpeg) and how to decide which to use.
