Work chain is:
Satellite STB
Hauppauge PVR-250
NanoPeg and/or MPEG2VCR
Ulead DVD WS (no re-encoding)
DVR-104
JVC XV-302

PAL!

Problem is:
I get jitter, strobe, whatever you call it, and motion "ghosts" everywhere, when capturing film. Ocasionally only, when true video (only at fast pans). And jerkyness with captured slow-motion video .

What eryone knows, Hauppauge PVRs capture bottom field first from video input. No need to tell, I have been desperate
It got very interesting, when I downloaded bitrate viewer. This is VOB from one of the film DVDs:

Num. of picture read: 26
Stream type: MPEG-2 MP@ML VBR
Resolution: 720*576
Aspect ratio: 4:3 Generic
Framerate: 25.00
Nom. bitrate: 8000000 Bit/Sec
VBV buffer size: 112
Constrained param. flag: No
Chroma format: 4:2:0
DCT precision: 10
Pic. structure: Frame
Field topfirst: Yes
DCT type: Field
Quantscale: Nonlinear
Scan type: ZigZag
Frame type: Interlaced

So, top field first ?!
(I warn You, it is going to be like TV-Shop )
This is not all. There are clear interlace lines on film capture, but they are gone in VOB! (MPEG2VCR). Also video capture looks like top first in VOB. Should (once again too far away from my home computer ) have been bottom first at capture.

What I think:
Field order has been changed during authoring and file header has been rewritten, but GOP headers show still bottom-first. Or vv. (GOP headers rewritten, file header not). However, my player (and all the others, I have tested) thinks, it is still bottom first and doesn't play correctly.

I really have no idea about MPEG file or GOP header structure, but as different field orders can be mixed, this comes to mind.

Am I right? What can I do to solve this?
