            Status: UNCONFIRMED

Using dvdreadsrc I came across strange failures, like the scheduler erroring 
out for no reason whatsoever, or  
 
   dvdreadsrc.c:516: _read: Assertion `is_nav_pack (data)' failed. 
 
assertion failures. 
 
Valgrind shows this (incl. gst-debug stuff for dvdreadsrc):
