The Samsung DTB-H260F can pick up digital cable channels that your cable company does not encrypt. This usually means the local broadcast stations (sometimes not all of them), plus a few odds and ends. These channels are available even if you have just a basic analog cable subscription. Plug your cable into the Samsung, do a channel scan and see what you get. You'll probably find that the local stations are on completely different channel numbers than what you'd expect, so look at the unit's channel list ("Ch. List" button on the remote) to see what you have.
You can see the menus and on-screen displays (such as the channel list) only via the HDMI and component-video (red/green/blue) outputs, by the way, not the composite (yellow) or S-video outputs. So make sure you're using the right kind of connection between the Samsung and your TV.
By the way, there's a long ongoing thread about this unit, and it's probably better if you post further questions there:
