Terratec Cinergy 1400 DVB-T digital TV tuner
 

I know plenty of people with TV cards that run an aerial splitter to get a signal on TV and PC, but with this card there is no need for a splitter. This would also benefit media centre owners wanting to run a dual tuner set up as you wont need to send two aerial cables to the MCE PC and would just need to take a cable from the aerial output of the Cinergy 1400-DVB-T card to the second tuner.

Would be better adding FM/AM radio tuner.
