Recording HD doesn't take much cpu, it is already compressed. It is the playback that takes the cpu. I use MythTV and a 500mhz cpu would record two ore three shows at once, but I needed a Pentium 4 and a good video card to play it back. All said, it should not be a problem. Do they have specs on their website? I use it on a Macbook Pro 2.33 C2D non Santarosa.
