A lo que vamos, en dvdtalk:

Ladies and gentleman, we have a new champion! The Collector's Edition and DTS releases from 2000 were great efforts for their time, but this new 30th Anniversary Edition meets or beats the originals in every department. Armed with a complete set of audio tracks, a ]more polished presentation and a near-definitive assortment of bonus features, this is the best Jaws gets on DVD. Owners of previous versions will certainly want to upgrade this time around: it's missing the trailer, but Universal's done a fine job of packing all the necessary stuff on this 2-disc set. There's a great deal of content here for the asking price, making this release a must-have for any DVD library. Be sure and pick this one up immediately---from top to bottom, there's no reason not to. DVD Talk Collector Series
