I have been having a consistent problem capturing from my JVC GY-DV500 camcorder. This only happens during a batch capture and never during a manual capture. This symptoms are as follows:
30%-40% of my batch-captured clips are garbled. See the sample frame here:

The visual garbage always looks the same with large grey blocks and skewed blocks of pixels. This spatial arrangment stays the same throughout the garbled clip and amongst multiple garbled clips.
When compared on the Vegas timeline with a clean capture of the same clip, the garbled clip runs about 20% longer on the timeline with the audio playing back at a lower pitch. For instance a clean clip that runs 1:53.06 plays back, in garbled form, over 2:15.22.
This failure happens on two different machines, each with acceptable specs.
This failure happens with camera tapes that were recorded with this camera.
Another related symptom is the odd naming and replication of clip files. With each captured clip, one of the following can happen:
1. The clip captures just fine and is properly named after the name in the capture list.
2. The clip is captured, but the file named after the clip is just the first frame or so and a second clip named Clip01.avi (or some sequential number) holds the actual footage. The start time of the full Clip01.avi clip matches the batch capture in-point but the out-point doesn't.
3. The clip is captured, but there are TWO Clip01.avi and Clip02.avi (or subsequent sequential numbers) files. The first Clip is one frame and the second Clip the actual footage.
Any of these scenarios updates the batch capture list in capture program and, subsequently write those changes to the .svidcap files, completely screwing up my original timecodes. I've taken to setting all of my .svidcap files to read-only so they don't get overwritten by the actual capture process.
Any thoughts or ideas would be most welcome.
