I just got the emailed newsletter, which states that everything is changing, and instead of buying a series, you will now just buy 6 months or 12 months. It also seems that there is no way you can buy the right to see episodes you missed.
I haven't bought series 3 yet, so it seems there is no way I will ever be able to see the episodes 301 - 09. This doesn't seem fair - I was planning to buy series 3 at some stage when I when finances allowed. In fact I am not in a position to buy a membership right at the moment anyway, so can't take advantage of the "offer" to get Nov - Dec free.
I'm a bit disappointed that now I will miss all of series 3 - I suppose I can wait for a DVD to be issued, but it would have been nice to have some warning of the impending change.
