what does the laptop have for video inputs? for instance i use my monitor to watch tv. component video cable from my cable box to my monitor, and optical cable from cable box to my surround sound. if all you have is vga input you'll need a tv tuner card. i dont know if they're available in pcmcia, but i would imagine you can get an external tv tuner. run your coax to it, and connect vga cable for video and rca's to surround sound.
