The DVD that comes with the book "DVD Demystified" has several trailers for THX, DD, etc. along with several sequences showing differences in bit rate, CBR vs. VBR as well as other good stuff. The book is also excellent if you are at all interested in the inner workings of the DVD specification.
Sorry if this was mentioned before, but the case and DVD Profiler both list this title as having a trailer - but where? Not a big deal (unless I'm going blind or something). Any thoughts?
