DVD drive init decoder fails

I am attempting to play a commercial DVD on a Sony Optiarc 24X DVD/CD
SATA Rewritable Drive under Debian Etch. I have libavcodec53 installed.

I issue the command:

$ mplayer dvdnav:// /dev/dvd5

(for some reason I don't have /dev/dvd, but only /dev/dvd5 and dvdrw5)

This produces the error:

MPlayer SVN-r31918 (C) 2000-2010 MPlayer Team
Loading protocol-related profile 'protocol.dvdnav'

Playing dvdnav://.

Playing /dev/dvd5.

This disk plays on a DVD player and is for Region 1. So I don't
understand why the decoder cannot be initialized. Am I missing some
software?
