DVD players that can record movies from cable?

Anyone knows of a good DVD player/recorder that can
a) play my movies from hard disk
b) record from the cable?

I got myself a Yamada dvd-recorder. Comes with built-in tuner, can play almost anything (except mkv) and has a usb and firewire port. When you plug in a usb harddisk it will recognize it and you can play the files.

Built-in tuner…does that mean it can take the cable wire and play/record the cable contents?
