picture rolls - rolling picture, vertically unstable

Well, I asked just a few short days ago the question of when I would
start hating this program like most of the others on here. I think my
question has been answered....

Last night I rendered a video of a friend's wedding. It worked great.
When watching the video on VHS, I noticed that I made a grevious
spelling error. I corrected it in the title and re-rendered the
video.

This time the picture rolls and is not vertically stable. On the Sony
digital camcorder screen, it is fine. It is when I try to tranfer it
to VHS that it rolls. Older tapes on the Camcorder do not roll
transfering to VHS, only this one.

I input the rendered video from the camcorder to my multi-standards
vcr and, except for lack of color, it converts as if it was recorded
in PAL format. The vertical sync seems to be at 50 hertz and not 60
hertz.

Has anyone experienced results such as this with MM2?

Thanks kindly,

Dave
