i feel like the main thing isn't the hard copy or actual dvd but that it is being able to watch media on your tv in a relaxed fashion, while sitting on the couch, chilling with crew, watever. Now many of us may already do this, u can download clips or videos from thrasher in .mp4 and usb stic that shit in your xbox and bang full screen quality watever its nice specially with the full length videos.
i guess the other aspect of the hard copy is that u revisit the video, which has many benefits. i feel like all tv's will start to play most formats widely available on the internet so people will have their collections on a usb stick or specifically designed ipod type device that will plug into your tv and play anything you may have (like a mini media player).
skate videos will have to be payed for by product placement and advertising - basically as they are now, the product has to be part of the video anyway bcos the product is skateboards and shoes and bro style grip tape.
