My TiVo Mini Vox has been working fine for about a week or so - but now whenever I leave it for a day it disconnects from the Bolt Vox it is connected to. If I try to play a show, it give me a C501 error, and when I go into settings and look at the host DVR it tells me my Bolt is incompatible. I messed around with it a bunch last night (C&D) and was able to get it working again, but tonight it had disconnected once again. I plugged my old TiVo Mini back in and it worked perfectly and the other TiVo Mini I have is also working great. Everything is running on the same software version - anyone have ideas as to why my mini is losing its host?
