To enjoy TV on your PC you need a product called a
TV tuner card.
There are PCI versions for desktop PCs, and external boxes with USB connections
for laptops. The tuner card allows you to connect analog cable, off air antenna,
and it has connections for a satellite or cable box. To use a cable or satellite
box with ReplayTV PC Edition you will need to make sure the tuner card has “IR
Control”, this way ReplayTV PC Edition will be able to change your
cable box to the correct channels to record your programs. The specific features of the tuner cards are listed on the unit!
