There may be a problem with the config file, but there also was no input
file specified. If you want to encode from standard input, you have to
use "-" as the input file. I would avoid the BSDvault article entirely,
since it has several mistakes and gives bad advice. The option "-vop lb"
is bogus. I assume the author meant "-vop pp=lb". Using a deinterlacer
on DVD material is usually a bad idea anyway. Specifically, one should
only deinterlace TV sources.
For film sources, don't use any filter if mplayer automatically reverses
the telecine. Otherwise, use something like "-vop detc=dr=1" or "-vop
ivtc". If the source is film, make sure to set the proper framerate,
such as "-ofps 23.976".
It's also a bad idea to use VBR MP3 in an AVI, since there are often
sync problems. A better place to start would be MPlayer's own documentation.
