Edie, I just noticed that I didn't really answer your question. I was really tired late last night so just skimmed through your post then. You were asking about video sales of the show, presumably without commercial interruptions, of "My skin Could Kill Me".
I can't find a retail source to buy a copy of the show, including ITV (UK), and TLC/Discovery. I suggest that you *call* the production company, Anglia Factual. The person responsible for "Sales - Rights Acquistions" for the show is a Jill Shawyer. Although her title suggests she handles the sale of broadcast/distribution rights to the show, she would likely be able to tell you if and where it is available for individual sale. I have listed her specific contact details below. Her name was listed as the contact for anyone interested in the Harlequin Ich show in particular, so you should feel at ease calling her.
