We're glad this card packs dual tuners, especially through a single aerial input, but there are a few things we don't understand.
First, it's based on the PCI-Express standard, which seems unnecessary seeing as how PCI is plenty fast enough to carry the signal from two MPEG2 tuners at the same time.
The other bizarre thing is that you can grab Terratec's far more versatile, but functionally identical, USB stick for the same price.
