What is the difference between dvd recorders and usb tv tuner for a laptop? - usb tv recorder

I want to buy one. However, I do not know most of what I found online. I want to know from personal experience, what would be the best buy? Hopefully tape a show on Monday, and I want to register in a position without any problems .. so any suggestion?
