jerked images after burning DVD

[Ilovm]

Hi there,

I am a IMAC user, work with FCP7 and DVDSP.

After compressing a FCP project with Compressor and burning DVDSP with DVDSP, I realized that scenes containing objects or people in rapid movement where showing jerked images.

The slow motion scenes are fine.

I checked the following

settings for DVDSP burning: VBR two pass;
averageBit rate 4,0,
max rate 7,0

1) the self-contained QT that I started with is not showing this problem.

2) the m2v file obtained from compressor (I use preset setting for high quality compression) does not show this problem when I view it with MPEG streamclip

3) I tried to burn directly the QT file with Toast 10 …get same problem if not worse !.
settings for Toast
automatic re-encoding
average rate 4,0 Mbps
max bit rate 8,0 Mbps
MPEG-2

I guess my problem comes from the bit rate I used ?

I am now confused and I am not sure I understood the impact of the bit rate setting on the quality of the resulting DVD, and I believe that using a high bit rate in DVDSP might result in problems for some clients to play the DVD on their player ?

Could it be something else ?
could someone please give me advice ?

Many thanks in advance
Ivan

sounds like reversed field order. interlaced video can be either top field first or bottom field first. find out what the source was and what the output was made as.
