Issue with transferring PAL VHS to my computer

[AllenR]

Hello VK friends,
I'm mostly an AK dweller but I'm hoping someone here can point me in the right direction with a video issue.

I just bought a PAL VCR bundled with all the extras to use here in the US. I have loads of PAL tapes that I recorded while living in the Czech Republic 1998-2003.

When I set myself up to capture the video onto my computer the video image looks great while recording. But when I am finished capturing the playback image has spots where color streaks appear that weren't there while recording. These streaks appear on the finished, rendered file. I've recorded three videos so far. The first one has this issue a lot. The second video is fine. This last video has the issue mildly in spots. All three videos looked perfect while recording.

So what might be causing this? Any suggestions what to do to fix this?

Thanks.
