I'm led to believe the sticking point is in the third series,the first two are owned by the BBC and i'm sure they would love to release them on DVD. The problem lies in the 3rd series,Jimmy Nail's own production company made the thirds series and the feature lenght special and i did hear he won't allow them to be released..which is why UKGold/UK Drama only ever showed the first 2 series on thier channels....it really doesn't suprise me,there are countless reports of fans going up to say hello to Jimmy Nail and him telling them to "fuck off"...i guess he still thinks he's in character(OZ).
