DVR Disappointment

It appears that my DVR is no better than a VCR when it comes to scheduling recordings. I set up to record The Tonight Show the other night, when George Carlin and Ann Coulter appeared. I figured it'd be great fireworks.

Unfortunately, the NHL playoff game went long that night and Leno didn't start until nearly midnight. I had hoped that since I programmed the recording via the on-screen program guide, the guide would have updated and I'd get my whole program. Wasn't that supposed to be one of the promises of DVR?

I got the entirety of Carlin's "solo" appearance, and about 5 minutes of Ann Coulter, with no sign of fireworks. Very disappointed.
