First pressings of the R1 DTS DVD version of Jurassic Park featured a defective 5.1 audio track. Universal has corrected sound and re-pressed the disc. The new pressing of this disc is now starting to appear in stores.
Unfortunately, there is no way to identify the new disc from its packaging alone. THE ONLY SURE WAY TO IDENTIFY THE FIXED VERSION IS BY THE NUMBERS ON THE INSIDE RING OF THE ACTUAL DISC. The FIXED disc will read: PEMC-D2R2. The earlier defective pressings should read either PEMC-D2R0 or PEMC-D2R1.
