actually, the technology exists that you can put a Bluray or HDDVD onto a 4g DVD disc and play it. though i have no idea how it looks, im sure there has some loss to it due to the compression.

regardless, let the MPAA, RIAA and whomever else throw in all the kitchen sinks they can into the encryption. please, throw it all in there - that way, it might take a week before someone cracks it (instead of a few days like before) and they can move onto developing movies that people would rather buy than pirate.
