Artefacts in rotated AVCHD

I have some AVCHD recorded sideways. I've rotated it, used Distort clip option to correct proportions, and rendered into DVD-compliant MPEG2.
Now, there are terrible wavy artefacts in all motion scenes. Any idea how to get rid of them?

You should not have recorded it sideways. Since you did, you must use it that way or rotate it and do not distort it, by stretching it to fit.

AVCHD is sensitive to motion as it is, so I suspect distorting it magnifies this.

Try using a method like Black Lab used for his ESPN style video. http://forum.corel.com/EN/viewtopic.php?p=183610#183610.

When converting it to mpeg-2, you also need to make sure you used Upper Field First as the field order i.e. the same as the original AVCHD. Changing field orders also introduces motion artifacts in motion scenes...

I.ve tried with a trial of another video editing software and no such problems. Another c*** on Corel' side.
