Hulu

So we've all probably experienced the case where, for some reason, our DVR misses an episode and we have to find it via another mechanism.  Sure, you can watch it on Hulu or Amazon VOD, but you want to add it to your collection without the DRM (exactly how the DVR would have done), and it came over the air/cable for free (or you paid your cable bill) - so why should you have to pay for it again?!   Maybe you've had one too many nasty-grams from Comcast about your bit-torrent downloads so you don't want to go that route.
