Should be pretty low.  It probably has to do slightly more work than the PVR250 because the nova-t has no hardware demultiplexing, so you have to receive an mpeg stream containing around 4 tv channels and seperate out the one you want.  This is mostly a chucking bits away type operation and we are talking about around 2 M bytes of data a second.

I will have a look at mine tonight if you want exact numbers, but I dont remember it being anything significant
