Repeat after me: halfpack is NOT a deinterlacer! In fact for real
interlaced video it will make the picture worse. The only time it
serves as a deinterlacer is with bttv's buggy fake yv12 output, and
even then it's not quite right.

If you want cheap deinterlacing, -vf field=0 is much faster and
actually correct.
But I'm not sure the problem is interlacing. IMO it's more likely to
be tearing that Tom is describing. But without a proper bugreport
(showing which vo he's using, etc.) it's hard to say.
