Using the Slingbox PRO-HD, you can connect to up to three home-theater devices, such as your DVR, digital cable set-top box, and DVD player/recorder to the PRO-HD. Also it will scan clear QAM (cable tuner) and ATSC (antenna tuner) channels. And if you have a high speed Internet connection, the picture will be very good even though you are not using HD cables like component.
