You forgot sometimes the broadcasters will screw with the start and end times of the programs just to piss off the DVR crew. I mean really, starting the show a minute early or ending it at X:31 PM accomplishes what really?
Oh, yeah, I can add additional time to my program when I set up a series to record but then you have three programs recording at the same time (the DVR only does two) and the DVR throws a fit and doesn't record one.
Getting to the point that it's easier to download the episode....
I keep seeing that Sony did this to 'send a message' to the hacking community. I'm betting that message will end up being 'post the hack/private key' as anonymously as possible the next time. Once it's out they won't be able to stop it and they won't have a target to go after.
Frankly, I'm surprised the guy that posted the Airplay key didn't go this route. He is just setting himself up for an Apple lawsuit which I'm sure is already on the way.
I realize that there is a certain amount of pride from doing this....but that has gotten rather expensive.
