I wish there was an option to make it so you have to hit "enter" to change the channel. I don't know how many times I've accidentally bumped a single number on the remote and the Tivo changes to a channel that doesn't even exist. Of course then you lose any buffer on the channel you were watching. Or is there a workaround I'm not aware of? I've only had Tivo for a couple of months. It's a Series 4 cable Tivo box. I also sure miss the Reminder function to remind you of an upcoming show you wanted to check out but didn't necessarily want to record it. Every other DVR I've had included this option. And maybe a clock on the face of the unit?
