Thank you!  Finally, I can stop depending upon MEncoder!

The docs appear to be wrong:
http://www.ffmpeg.org/ffmpeg-filters.html#fieldmatch
-vf fieldmatch=combmatch=full,decimate
Causes major audio sync issues, however, using mpdecimate instead works 
perfectly:
-vf fieldmatch=combmatch=full,mpdecimate

Also, I was hoping I could do some kind of auto combing feature like 
Handbrake has by using the line below, but it causes major audio sync 
and frame skipping issues:
-vf fieldmatch=combmatch=full,yadif=deint=interlaced,mpdecimate
Is there any way to do what Handbrake does?
