Strange problem with capture from VHS to DV

[s2001]

Hello,

I captured a lot of VHS tapes from VCR -> DV Camera -> PC...
But I have very strange problem with last PAL VHS tape:

- picture is nice on the TV screen when played from VCR
- picture have a lot of horizontal artifacts when it captured to DV

Could you please check example and help me to find the problem source?

Looks like either an interlace problem or a field order problem. I'm leaning toward an interlace problem because it looks too extreme for a field order issue.

Perhaps the DV camera thinks it's a progressive source and it's really interlaced? Is there a way you can change the setting and try it?

Thank you for your reply!
Unfortunately my JVC D50 DV camera have no interlace/progressive input settings...Could you please tell me, are there other ways to fix the problem?

I looks to me more like a bad synchronization problem of the tape.
Most TV sets correct such things so you don't see it there.

What kind of tape is it?, A copied tape?
If possible you could try it on another VCR?
Or else only a TBC would help i think.

Are you by chance using a Canopus ADVC50 or ADVC100 for your DV captures?

Could be an issue related to Macrovision.. Some of the older tapes are sometimes wrongly reported as copy-protected and therefore the capture card scrambles the signal.

On the ADVC50 removing the last jumper is supposed to get rid of the macrovision thingie.
