I think both formats suck. DVDs and anything resembling a DVD is a hoax played by the studios so that people can 'own their own video store'. What's the point? The number of times you would watch the DVDs cannot justify the cost. And if everyone has a video store what's the point? Whatever format you choose to embrace and collect will be obsolete in a few years anyway.
But all those reasons against owning your own DVD style collection pale in comparison to the fact that all this content should be streamed from the net anyway - we should all have access to all content all the time. Anything short of that is a joke on consumers.
