I haven't been able to read the news sites as of late. Perhaps this information has been posted there previously. Our contact at UHV has sent me this statement asking us to post it for all of you.... Some listeners have noticed that the initial release of the Jurassic Park-DTS DVD differs in bass level from other home-video versions. While every effort is made to maintain accuracy and consistency across various releases, source and process issues sometimes lead to differences which are noticeable in direct comparisons. Universal Studios Home Video strives to ensure customer satisfaction, and accordingly has implemented a running change for this title, using the original master soundtrack. The earlier production run can be identified by the code number D2R1 on the inside hub. The newer, current version can be identified by the code D2R2 and will contain a red technical grid on the back of the packaging as part of the running change. Consumers who have purchased the "D2R1" discs will have the option of making an exchange. Please send in the disc only (without packaging), along with name, address and telephone number, to: Universal Studios Home Video, PO Box 224468, Dallas TX 75260 or Universal Studios Home Video, 8801 Autobahn Drive, Dallas, TX 75237. Please note: This offer for exchange applies only to the DTS version of Jurassic Park.
