Top field first should be the default for mplayer. IMO here's a
correct way to do it...

1. If the interlaced flag isn't set in the mpi, treat all frames as
   tff (most sources are tff). Optionally override by config var.

2. If the interlaced flag is set, use the tff flag from the mpi to
   decide which to do. Also use the rff flag! Unfortunately this is a
   bit broken, since mencoder can skip/duplicate frames without you
   knowing.... G1 is really really broken.. :(
