jerky movements with .MTS files

Hi

I know next to nothing about video but was pleased to find that I could 
easily edit the files of my canon hf200 into a "real movie" with kino. I 
then made a DVD with mandvd, but watching the result on my 42" HD LCD tv 
was quite a disappointment, unfortunately. When there's movement in the 
video, it's quite jerly, like the movement goes a bit in the right 
direction, a tiny bit back, a bit in the right direction, a tiny bit 
back and so on. It's doesn't look like camera shake, esp since 1) the 
camera has image stabilizer and 2) the videos play back just great with 
the camera connected directly to the tv via hdmi.

Although the result seems worse on the final dvd on the tv, there seems 
to be already traces of the problem in the .MTS.dv files made by kino 
upon import. This leads me to believe that the problem is in fact in the 
import process, handled by /usr/share/kino/scripts/import/media.sh. I 
looked and it seems that media.sh converts the video to either 25 fps or 
30000/1001 fps. I looked in the camera menus and the camera is set to it 
default frame rate of 50i, setting it to "pf25" (I asume this means 
non-interlaced 25 fps). A quick test suggests that setting this to 
"pf25" gets rid of the problem, but that was a really quick test, so...

In any case, it doesn't help with my 400+ files already recorded on 50i. 
So, I'm looking for any advice on how to get rid of this annoying 
problem. Any thoughts or anything I should try? I could mail a 
problematic .MTS file, it that would help in tracking down the problem.

NB: I noticed that when exporting the video (at least with "YUV 
film-like") kino outputs "Stream is interlaced, bottom-field-first" in 
the terminal, dunno if this information is relevant... However using 
"YUV film-like" when exporting (to mpeg/0-DVD) doesn't remove the 
problem on the resulting dvd :-(

Any input would be highly appreciated!
