Like you I heard some of it - basically there were two people on: one was a slaughterman and butcher and one sounded like some mate of the producer who was there to stir things up and my take on him was that he was getting paid as a troll. From the bit I heard the butcher made all the points you'd expect which is to say hygene, safety, was the poached beast medicated and so on while the other bloke said he bought lots of his meat, including venison, from blokes he met down the pub. The item wasn't just about venison and in fact the focus of the link was on the fact that lots of sheep are now being stolen to supply a black market in meat. It just so happened that the nutter bloke claimed to have bought just about every type of meat known to man down the pub and that is where venison got introduced. I am also pretty sure that a lot of it was untrue as the nutter bloke had difficulty with even simple questions about the circumstances of his purchases and provided very little detail or background so he really wasn't convincing at all.
As an aside I had some deer poached on me about 2 years back. For some reason although the poachers removed some carcases they left one complete deer lying dead in the ditch. They returned 5 days later and butchered this carcass where it lay. My money says that venison was sold to some bloke down the pub and I'm amazed there wasn't a death, maybe there was. The police were provided with the name, address and vehicle details of the poacher at that time, and on several subsequent occasions, and he is still blasting away at eyes in the lamp when it suits him with the police of the view they "can do nothing about it."
Now, I am sure that if you were to interview the same nutter bloke about people shooting at eyes in a light at night he would be exploding with rage, in fact being the Vine show he is probably totally opposed to private firearms ownership. Equally if you were to interview him about food safety he'd want a whole range of laws to protect his children etc. and yet there he is speaking out in defence of organised poaching for cash.
