Ive had my Tivo Premiere for a little over a year. I was getting the 14.8 freezing up issues this past week, today my Tivo gives me nothing but a black screen. When I reboot the Tivo, I get the "welcome starting up" followed by the new just a few minutes more screen. (It only takes about a minute for the 2nd screen to come up). - The green light is on and the yellow light flickers for a few seconds The few minutes screen is on for about 10 seconds, flickers, then comes back for about 7 seconds then goes to black. From there nothing, nada. If I listen to the box, I can hear hard drive activity but there is no response from anything else. Any ideas or suggestions?
