[MPlayer-users] AV sync problem

Sure :)

I'm sure. if mplayer needs -nobps, it means the files are unplayable with
avifile or windows media player... it's an extra feature of mplayer to
handle broken files with bad header.

-ni is not problem for other players, as they use it by default (or usually
only method). let me explain.
- interleaved avi files (no -ni needed):
  you need only 1 streaming line, you can read the file linearly and process
  data. it speeds up file i/o especially for cdrom.
- non-interleaved avi files: (requires -ni, usually autodetected, except for
  some broken, badly interleaved files):
  it requires 2 independent streaming line. one for audio and one for video.
  it means you have to read the file 2 times! bad for network/cdrom.

so, both -ni and -nobps are to workaround broken stuff. i mena broken files,
not broken player :)
