You could try VLC. ;-)

Well, more seriously you could try dvd:// instead of dvdnav:// and use 
some cache (I use 4MiB). For a DVD containing several episodes you 
likely need to find out which titles to play. You can use the -identify 
option for this:

mplayer -noconfig all -cache-min 0 -vo null -ao null -frames 0 
-really-quiet -identify dvd:// 2> /dev/null

This prints, among other info, the titles found and their length in 
seconds. You then specify the title to play (say you want to play title 5):

mplayer -cache 4096 -vo vdpau dvd://5
