Don't forget to install the -dev package. If you have to specify any
special options it's a bug in MPlayer.

Well, you were right. The dca decoder from libavcodec does not yet work
correctly in several cases, DVDs being one of those - essentially
because MPlayer does not use the code in dca_parser.c.

That is very weird, and is not what is supposed to be necessary.
Instead of "wasting" your time, it is usually better to send us the
section of configure.log that tests for whatever you think MPlayer
configure should enable but does not.
