So I've had a TiVo HD for about a month now and it's been generally great. I'm using it with Millenium Digital in Seattle, which is probably the worst cable company in the history of cable companies. Nonetheless, it has been working well. Today, all of the sudden, I couldn't access some digital channels (they went "grey"). I can't tell a pattern to it, but it seems to be all of my premiums (HBO, Sho, Sports HD tier), and a few non-premiums (NBC HD, for example). The cable company is closed tonight, so I can't do anything with them. Any suggestions on things I can check myself until I can get in touch with them? Thanks in advance!
