Looks like the Win HVR 1700 model 236 is the only option as the 2nd link to the Lifeview card does not show any available in Ebay or via a google search. It also only has drivers for XP and not Vista. However the Win card is OK and I will look at it more closely re reviews etc Thanks anyway
Hauupage is pretty good , I have 3 of their cards already. Unfortunately the win TV 1700 is out as it has no built in decoder for sat and needs a separate set top box to receive sat. Not surprising as it is a 2005 card . I will probably have to settle for a dongle or else take the chance and install a PCI card next to the 4870 GPU. it is an Antec 900 case so the cooling is pretty good anyway
Just to tie off this thread . I have ordered a Compro DVB-S500 tuner which is a USB device that gets good reviews. Seems we will have to wait a while for PCIe sat cards. Compro software is a bit clunky but this is Vista 32-bit compatible.
Stuartli-- many thanks for your persisent and useful research. With an external box I can forget about cooling air flows on the GPU-and it is ordered now.
