It was only a matter of time. What was once the ultimate convenience for TV fans has now been labeled as an affliction. Brad Berens of iMedia, a company that analyzes the way advances in media impact people's lives, had identified the responsibility we feel when we TiVo or DVR a show or series and then don't get around to watching it in a timely fashion as "TiVo guilt."

I can't disagree. I don't know about you, but I'm always checking my DVR list to see what's stacked up that I still have to watch. It's not that I feel like I have to watch these shows -- after all I recorded them because I want to see them -- but there is a burden attached.

According to Berens, what I'm experiencing is called "opportunity costs," and my TiVo viewing has become -- believe it or not -- homework!
