PVR from 2 sources at once?

[videobliss]

Hi,
Does anyone know of any product that will allow me to record multiple tv channels at the same time? Multiple cards would be cool as long as they don't conflict.

I'm leaning towards the ATI AIW 9700 with an additional TV Wonder card, but it sounds like you can only do picture-in-picture with it, not recording from multiple sources at once. Any ideas?

Thanks.
