I was mistaken it seems libdvdnav is all around broken. I get the same 
thing on my MPlayer build using the mingw.org compiler and I tried 
Subjunk's SB46 release today and it to failed same error. I reverted to 
r1243 and it went away. I updated to r1245 and the error reappeared. 
Can't play anything at all!
