Help clarifying render to VHS and field order...

I tried my first render to VHS and the results were bad to say the least. An fast horizontal movement resulted in the image breaking up or jittering. Looking in the manual, I saw that for TV, I should use upper field first. I tried this and got the same result.

Rendering the final AVI as progressive produced perfect output to VHS. Is there a difference between NTSC/PAL that caaused this or should upper/lower first work?

Just wondering if I should hunt down the problem or leave well enough alone?...

What is your capture/print to tape hardware?

I tried two methods using both 'upper field first' and 'lower field first' renders:

1. Render back to the camcorder and then print to VHS using it's video output.
2. Render direct to VHS using a Canopus ADVC-100 A/D converter.

Output was sent to the VCR usng composite connectors in both cases and both exhibited the same problem. Both upper/lower field renders recorded and played back fine on the camcorder - it is only the transfer to VHS that seems to suffer.

Having some more time to think about it - by 'jitter' & 'breaking up', I guess I really mean a very bad combing effect on any horizontal movement.

The footage came from a Panasonic NV-DS28 camcorder and was captured with Video Factory's video capture utility (V2.5). All edited in VF2.0c under Windows XP Professional and rendered using the 'Make Movie/Print to DV tape' option. Everything was set to defaults.

I tried with the project set to DV PAL and then again with the project settings at DV STANDARD.

As mentioned before rendering with the field order set to progressive prints to all devices without the jitter/comb effect so I seem to have the answer - I'd just like to work out what the problem is... :-)

Thanks,
