   You should call dvdcss_crack each time you change title or layer. I
don't know if the Xine IFO parser is title-aware yet, but if you don't
call dvdcss_crack there is a chance it'll work, since most DVDs only
have one key for the whole disc.

   Yes, all VOB files are block-aligned. And so is their size.
