Oh sorry I forgot to get back to that question - I couldn't find anything about that story, so I think I must have missed a few episodes. I discovered after your previous q that there were some episodes on C4 which I thought were repeats but weren't (so I missed them).
I only "own the tapes" in the sense that I recorded the original run of episodes directly from C4 when they were first on, about a year and a bit ago. You might be able to find out about official videos or DVDs through www.seanmaguire.co.uk - there might be links to the American TV company somewhere. So I can't help unfortunately :-(
P.S. Sean Maguire is gorgeous (did I say that before?).
