I love DVR. Love it. Prevents me from having to suffer through my wife's shows, "American Idol" or "Lipstick Jungle." But what I hate about it is how some people use it for sports. I know several fools who wait until games are over just so they can watch them really quickly. Something important will happen and I'll call them, only to be told not to say anything that's happened in the game because they're recording it for later.
Only for something as redudant and meaningless as baseball would something like that be OK., But for anything important, such as the NFL or college basketball, the practice is absolutely insane. It's like saving all your newspapers during World War II and waiting until it's over to read them all and find out who won and how it happened.
