Since I've gotten a couple of emails and IMs about this: yes, unless you're in Australia, you will need a multi-region DVD player of some sort to play the Blankety Blanks DVDs, as they're Region 4. I'd rather not turn this into a tech support board, so here are a few pointers to at least get people started...
As I said earlier in this thread,
Videohelp.com is an excellent source of information regarding which DVD players are already multi-region and which ones can be customized to that end, either via hidden codes or firmware upgrades. As software players go,
VideoLAN Client works fairly well; it's not perfect but it's free and it's available for numerous platforms. The aforementioned Videohelp.com site also has very informative discussion boards where you can ask all the questions you like about any of this. :-)
