[MPlayer-users] enable libdvdnav cacheing?

[Roger Pack]

Hello.
I notice when using dvdnav:// this warning message:

Remember to disable MPlayer's cache when playing dvdnav:// streams
(adding -nocache to your command line)

so I do.
I've also noticed that mplayer's DVD playback performance is a bit
poor on slower computer.

Also I notice in

stream_dvdnav.c:

  /* turn off dvdnav caching */
  dvdnav_set_readahead_flag(priv->dvdnav, 0);


VLC seems to enable it

  dvdnav_set_readahead_flag( p_sys->dvdnav, DVD_READ_CACHE )

Anybody know the motivation for turning it off in mplayer?
Thanks!
