My 1st contact point was ITV Sales & received the below reply on 30/03/2010:-
"Thanks for your enquiry.
I'm afraid that this title isnt available as a commercially-released DVD and we can't supply one-off copies of whole series.
However, it should be possible to produce a DVD copy of a couple of episodes for private and personal use. The price would be 95.00 GBP per 30-minute programme.
Please let me know if you'd like to proceed and if you have a preference for any particular episode(s)."
With 26 episodes @ 95 quid each I reckon it would cost in the region of 2 & a half grand to get the whole 3 series, so my reply back to ITV was:-
RE: Brothers McGregor. (1/1200).
"Thanks for the quick reply.
I wont be proceeding any further.
But may I suggest you recommend that the 26 episodes are released onto a box set, as Im sure it would be very popular".
