I'm affraid I voted "no". In essence it's a very good idea, but I think the cost is too high.
Why do I think this, well, I have the same opinion with many of the cable & satalite T.V stations. Some of them are good, but many are poor. Add to this the fact that many stuff is repeated or does the rounds, so to speak, on different channels, so, at least initially, the cost would be high for the amount of programming avaialable.
O.k, say you want to buy a DVD on servicing a certain air rifle that would cost you £9.99. If a person pays a monthly fee, even if it's just £5, he can watch the DVD as many times as he likes as long as he keeps paying, but once he has bought the DVD, he has it for life, so to speak.
I think the idea is a good one though, just a tad pricey, however, if copyright is involved, I can see why it costs so much.
Cheers.
Chris.
