Stupid BBC. They are just encouraging people to use BitTorrent and into the realms of sharing high quality copies as opposed to the relatively low quality of YouTube vids.
There's already someone on this thread offering DVDs - To distribute those DVDs would be illegal as the law stands, so be careful! But, the BBC are encouraging people to flout the law by doing stupid stuff like this.
The media companies should be embracing the harmless sharing of relatively low quality YouTube vids, otherwise the masses will learn how simple it is to freely copy & distribute high quality digital entertainment formats.
Copyright law can only be maintained in the digital age if the large majority of the people agree to adhere to it, even though they have the means to flout it. As soon as they lose the people, the law will be worthless and the media companies will need to find an entirely new business model, one not based on intellectual property. If that's what they want, they are going about it the right way.
