Can I Buy A Cable Card For My Tivo. Although, some of the newer ones can handle more than on channel at a time. Some packages and channels will not come through without a box.
You can pick up a cablecard at your nearest cable service center, order one from your cable provider, or have a technician bring one to you (fees from your cable provider may apply). I recently went to get a new cable card for my tivo. Locate the cablecard slot on the back of the cablecard capable device.
