Hello,

I see that some movies such as Mr. Peabody and Mr. Sherman have two title selections for 24.3GB both are 28 chapters - one has many more audio tracks source 00801 or 00802.mpls. Does it matter which you select?

Most likely, 801 is the US version, and 802 is non-US. The difference would be in signs and titles, and the extra tracks are for different languages. Easiest way to tell is to watch the titles portion of the movie.
