DVD2 only contains OpenOffice packages. Unless you need to install these from the DVD, you should be fine without DVD 2.

Just finished downloading the DVD with bittorrent. Ended up with two iso files (1 of 2 and 2 of 2). sha1sum checks out on both.
This is the first time I've encountered two DVDs. Will the install politely ask for DVD #2 when it is time?
