 Here are doing two Satelco EasyWatch (KNC One clones) their job for years, but since my new vdr hasn't got any PCI
slots anymore I switched to the cards from Digital Devices/Linux4Media. A (dd)bridge and two Flex modules (=> 4 Tuner)
are working for some months now. You just have to compile the driver from the media-build-experimental repository of
Oliver Endriss - if you use Ubuntu/yaVDR there is a DKMS package which makes installation easy.
 They are a bit more expensive than other cards but have advantages: the dual tuner module just needs one cable and it's
no problem to connect a second module with a short cable from the antenna output of the first module. And since they are
small cards it's just a matter of the slot bracket if you want it full or low profile.

Regards,
Lars.
