I tried the -vf yadif but there was no change in speed.

Well, I don't know or would not know how to find out. The video files
I'm working with are from a Sony HDR cx220 video camera. It produces the
above mentioned avchd .MTS files.

The good part is the transcoding to mpeg works perfectly (so it seems)
so I can't complain.
