Its even worse when someone else has stuff you know they will never get around to watching, and you are short on space. Seems the more shows I watch and delete, the more that free space fills up with the other people's crap!
I have developed one compulsive disorder for sure... Commercial Phobia! I have gotten so spoiled watching recorded stuff, and FF'ing through the commercials, I can't go back. If I am in the living room, and "House" comes on at 8PM, I will either go do something else for a good 20 minutes, or desperately look for something else on the DVR to watch. I have gotten to the point where I literally just can not watch live TV with the show interrupted every 10 minutes with 2-5 minutes of commercials!
If walk in the living room and something interesting is on, I ask if it is recorded. If the answer is no, I grab the remote, hit the record button, and go do something else, and will go back and watch it at a later time.
