The DVDs are not fully patched up, but they are fairly close. The Burning Crusade CDs we got back in January last year are patch 2.0.1. We're up to patch 2.4.1 now. More recent CD/DVD pressings may be closer, though. Take a look at Patch mirrors for instructions and advice for getting patched up the most current version of the game. The game will patch itself up if you let it.
Additionally, your user page isn't the place to ask questions on the wiki. Feel free to try the Warcraft pump for any gameplay/lore-related questions, the Village pump for any wiki-related questions, or the WoW forums for your locale. --k_d3 23:06, 15 April 2008 (UTC)
