There are DVDs out for them that come out in the UK for those. I *think* I even recall that they're not region-specific, so you can play them on any regular US DVD player, but I'm not certain about that.
The problem is I've seen it listed in different places as Region Free and in other places as Region 2, hence without the actual DVD to test, it's impossible to know, and I don't want to spend the money to find out
