I recently visited Best Buy and decided to purchase a Hughes DVR80. I'm not really all that interested in recording something while I watch something else or recording two things at one time. All I really want to do is just record the seasonal stuff that I watch on HBO, i.e, The Sopranos, The Wire, stuff like that. My dish does not support dual connections, it's the standard one receiver hookup. Can't I replace my primary receiver now with this unit and still use Tivo to record my shows when I'm not at home or late at night when I'm not watching t.v. anyway? I also heard that you have to keep the unit plugged up to the phone line at all times, that true? If anyone could elaborate I would greatly appreciate it, I really want to use this box, just not interested in the dual recording, and the extra stuff. Any suggestions?
