ffmpeg does not use liblzo since it is GPL. It uses my own lzo
implementation for some codecs.
MPlayer does not need the lzo library either (AFAIK), since minilzo
is included, and I doubt you'll run over a media file that needs it.

Uh.. for playing, MPlayer does not have any choice, it must use whatever
was used for encoding. Also, lzo is hardly ever used for encoding video
these days, at most for video headers (matroska can use it), but even
that is rare.
Actually a quick grep for USE_LIBLZO delivers only vd_lzo.c and
demux_mkv.c...
