I would like to build a Windows MCE PC and one of the main functions will be to use it as a PVR What is the best choice in TV cards ? I am confused as there do not appear to be any Digital Tuner cards with hardware PVR support. The only ones are the analogue ones ! Is there a reason for this or is it because no one has brought one out yet ? I am under the impression that onboard hardware support for PVR (encoding) will reduce the burden on my CPU and this allow me to use a smaller case as there will be less heat.
