Camera tracking interlaced footage? (Motion tracking)

i’m not sure what forum to post it under so please move to the necessary one.
I have a video camera that films interlaced footage, within blender this is very hard to track, and can take hours just to get a simple track working as the interlaced parts send the markers in all kinds of directions.
Is there a good tutorial or some setting i could change to make my life easier without having to go into other software?

Load the clip into the Video Sequence Editor, and render it out (as a movie or image sequence) but be sure to check the De-interlace box in the Filter panel in the VSE. (hit the ‘N’ key to bring up the tool panel if it isn’t already showing.)
