There are several versions of this DVD available. The newest release is;
Studio: Starz / Anchor Bay DVD Release Date: December 18, 2007 ASIN: B000WC38DM
Look for it here on Amazon.
This release is also by Starz / Anchor Bay (DVD Release Date: January 30, 2001), but apparently some people have had skipping issues with this version (see the other reviews). Also, avoid the other releases which are cheap for a reason; most are full screen and poor quality transfers. Some even have the opening "computer text" removed.
I own three DVD versions and my recommendation is to go with the newest (2007) release!
