 That was because height was not a multiple of four (error message
 committed to MPlayer, will be merged).

 The filter works in the sense that it can remove interlaced frames from
 telecined content, unfortunately it breaks AV-sync for longer samples.

 Note that the filter only supports yuv420p and I believe this is unlikely
 to change soon (it simply does not work for v210 samples if you don't
 change the colour space).
