Green stripe on left side of captured video screen. How to remove?

[videomatrix]

Hello,

I have a situation where I am trying to capture an old VHS tape of a school celebration. Video tape was captured from the event many years ago by professional cameramen, who then took the raw footage and edited it according to music.. that sort of thing. This was in 1990 and it appears there is something like macrovision on the tape. I tried to capture this video which was a "shifty" picture in the WinDV capture software window.
Fortunately, I have a device called a "COM World Digital Video Converter System" which I used years ago to convert PAL tapes to NTSC when I watched PAL tapes on my NTSC TV. That device apparently has a feature which removes the macrovision, not sure if that is intentional or not.
The PROBLEM now is that the video captures, and the "shifty" picture/macrovision appears to be gone, but there is a strange troublesome thick green stripe along the left corner of the screen. I have attached this image called 'Green_Video_Capture.jpg.'
My setup is as follows. I have a Sony VCR which connects to the "COM World Digital Video Converter System" (which deletes the macrovision) then to an ADVC 110 analog/digital converter. Then that connects to my HP Pavilion DV4-2045dx x64 laptop running windows 7 professional x64 via my Dynex Firewire 800 ExpressCard Adapter (1394a). I capture the video using WinDV v.1.2.3 and save the captured file to an external 2TB eSata G-Drive as a single file. I have at least 20 or so other files I've done before this saved as Uncompressed .avi max file size of 294GB in a single file, but average file size of around 30GB or so.
In this case alone I am getting this green stripe which you can see in the screen capture of this resulting video that was captured on the first attempt which I was playing back in VLC media player when I took the screen capture snapshot. The green line should not be there. Any ideas how this can be eliminated, or what is causing it?
The only final thing I can offer as an observation is that without using the Com World device to strip the macrovision is that the screen, as I said appears shifty, but that green line is mixed in there with the shiftiness. The green line and video all appear to shift horizontally in the shape of a letter 'Z' across the screen. There is NO green line on the left side in this scenario.
When the ComWorld device is turned on, there is no 'Z' shiftiness at all. The picture is 100% clear. The green line stands vertical on the left side for the duration of the film. That's the issue. Thank you.

That's not an uncommon problem. You can just overlay a black bar over it. Or crop the frame (and maybe add back a black border, depending on what you plan to do with the video). Use whatever editor you want that supports those operations.
