Goddamnit. I was trying to work out the downside to this scheme
And then, as usual, it turned out to be %^&*ing DRM.
I think I'll stick to ripping my discs at home then. If you're going to charge me for the privilege, I expect full control, not a licence. Especially not a licence that some greedy gimboid can rescind in future for no real reason other than "we'd quite like you to pay us again for that film, please". (Same major fail underpinning the "digital copies" provided with DVDs - the only film I own that came with one was Predators, and the small print advises me that my licence for that film will expire 2 years after I validate it...)
