Hi,
I captured some videos and some have yellow lines like this, you can see them well when there is the sky (because it's blue).

Taken with
"VCR" JVC HR-S7965EK -> "DVD&HD Recorder" Pioneer DVR-440H -> DVD
I've also set TBC ON and BEST ON on JVC.

You would want to check whether it happens using a different VCR, and a different capture device or a TV. It could be the tape that is bad, it could be the VCR, it could be the recorder, it could even be a bad cable.

I've not seen this happen with my Pioneer at least, and never heard of the JVC players causing such an issue. It seems more likely that it's on the tape, but I could be wrong.

Chroma noise (stains, rainbows, blotches, etc.) are common with many analog tapes, especially when stored under less than ideal conditions. I've seen those glitches even on "new" retail tapes.

There are filters designed to help clean chroma disturbances. But if you intend to apply any cleanup, restoration or repair techniques you won't get there by capturing to lossy codecs. Direct-to-DVD recording with old VHS tapes is one of the worst capture methods. Video made with lossy final delivery codecs aren't designed for further modification without serious quality loss.

Thank you for your reply.
During the capturing I also have a TV and the yellow stripes are present on the screen too.
Then I record all the videos in XP mode (near 4 GB per hour) on Pioneer hard drive.
However, I'm waiting for the "new" PC where I can install Windows XP (or Vista) and my "brand" new AIW X1900.

Chroma noise, a flaw in the tape signal, common on all VHS. Sometimes worse, sometimes better. Usually worse.

LSI Logic based DVD records (not Pioneers) would remove it.

Or capture lossless, filter in VirtualDub (use Camcorder Color Denoise filter).
