Well, if you don't want to record from one to the other, daisychain the two PVRs - aerial downlead into one, RF out from that into input of the other, RF out from the second one into the TV, and then HDMI out from the Panasonic to the TV and Scart from the Daewoo to the TV.
I'd put the Panasonic ahead of the Daewoo in the chain, as it's capable of making better recordings.
