I was reading about the DVDR TV recording capabilities of Windows 7. I'm not sure what I would need to be able to record TV on my computer using Win 7.
What is a TV tuner? Is my monitor the same thing? And getting a separate connection to my cable system, how does that work.

Can this be done with a Asus netbook that is portable and can be connected at the same cable connection site as my TV's.

Is Windows 7 different enough from XP that everyone will be updating?
