Strange TMPGEnc phenomena

[Phoebos]

I cannot understand why the mpg file (coming from encoded avi by TMPGEnc) is ok and after authoring (TDA) DVD shows jerky movement. When I say jerky is jerky, in every movement of the camera I see tremlbing.

Other mpg files on same sequence were done with the same way and look fine on DVD. When I watch the DVD image with PC with PowerDVD its also ok. On TV its Parkinson desease.

Was this just a strange phenomenon ir there is an explanation?

What's the aspect and framerate of the source?
Are you encoding to PAL or NTSC?

Yes, we'll need more info. A couple possibilities: interlaced and field order got reversed, used pulldown on interlaced material, NTSC 23.976fps and didn't get the pulldown flags set.

Thank you for your responses. The matter concerns VHS PAL captured material thorough capture card to avi files. Resolution was halfD1= 352X576. I then apply filters with Vdub and then frameserve to TMPGEnc and after I feed TDA with the produced mpg files . Field order is always top. I do this all the time, actually this DVD had other mpg files with no problem.

Tried encoding as BFF? Although I don't know how this could happen on a capture. Is there any way you could post a short clip of the capture and/or the m2v?
