Hi, Two of my three DSR6000's are behaving badly. I've swapped drives, cables and versions to no avail. I've tried the original drives and have made 2 new tivo drives from scratch. Each and every time everything works as its suppose to. I get live tv, recording works and it successfully can be rebooted without disconnecting the sat cables. Then for no apparent reason it drops out of live tv and has to re-acquire information. It gets to 100% and just stays there. I can get to any of the tivo central menus, but no live tv. Any ideas?
