I just picked up at an auction a "President PS 700 XL" Satellite Receiver. It came with another module PS 700 AT with remote control. Its like new condition and I do not know what it does. I googled it and no info found. On the front of this unit is "Video Cipher 2 Plus". Anyone have any ideas what this unit does? I wanted to sell it on Ebay but don't know how much and for what use. I am sure there are satellite gurus out there who know exactly what this unit is and I would appreciate any and all information. thank you for the help
