Networks HATE DVR technology, 'they're stealing our profits' or some nonsense, and they're worried about people having digital copies of their shows and being able to send them on the internet, so they intentionally mess up the times so you've got to spend 1h and 2 minutes to see a 1h long show...
They're trying to punish people for not being ignorant about technology and it sucks. Probably why I rarely watch network tv beyond the local news...and price is right, god those girls get hotter and hotter, bob barker is a god...
