I have a series 3 Tivo with 2 Cablecards from Comcast. I've had a few problems with them over the years.. but nothing too bad. Yesterday, I tried to go to live TV, and got this message: "Upgrading Cablecard 1.. press select for more info. Cablecard firmware upgrade in progress" When you click 'select' it tells you the upgrade should take about 40 minutes. But what happens is that after about an hour, the error message goes away, live TV comes back on, and then right away the message pops up again, starting the cycle over. Over and over and over.... I have tried rebooting, turning it off and removing the cablecards, then re-inserting them, calling Comcast, etc.. nothing is working. Any ideas? I'm dying without the NBA playoffs right now... Thanks!
