what actually does start over mean? do you have to be on a live buffered channel for so long for it to work? i notice alot of them has the triangle sign beside the channel in the guide? it sure doesnt work like twc start over works, you change the channel and if it has start over on it you can push a button and it will start the program over no matter how far you are into the program, this is a great feature for twc along with look back where you can view certain programs up to 3 days ago.
