I have a refurb Premiere I bought from Woot over a year ago. It's been unopened in it's box until a couple of months ago when I hooked it up and started using it unactivated as an OTA tuner. A couple of weeks ago I called to activate it as the second Premeire in my HT setup (and to convince them to give me the $99 lifetime deal on my month to month TiVoHD). It's been working great but I've only been using it with an antenna. A few days ago I decided to go ahead and get a cable card for it (I have Comcast service and my other Premiere and my HD are both on it already). I powered it down and installed the M-Card but when I powered it up it never would get to the setup screen. I'd get the "We're almost there" screen but it would eventually get to a blank blue screen with nothing but the TiVo guy in the upper left corner. I could hit the TiVo button on the remote and it would cause it to reboot again and eventually end up at the same screen. I assumed it was an issue with the M-Card and sure enough when I removed the card everything worked fine again. So I went by the Comcast office and told them I had a bad card and they gave me another one. I came home, put it in, and guess what?...same thing, same blue screen with the TiVo guy in the corner. Again, I removed the card and it worked fine. I chatted with TiVo and they told me it sounded like a hardware issue and to call them to see about getting a replacement Premiere. They were pretty much no help at all. As a test, would I lose pairing information if I were to try the M-Card from my working Premiere or HD just to see if the unit will get to a setup screeen and verify that my box is good? Could I install the questionable card in one of my working units to see if they boot up to verify that the card is good? My gut feeling is that I got two bad cards in a row but I want to make sure if possible before I go to Comcast for the third time. I should also mention that this second card I got looks like it's been well used. Thanks in advance for any assistance.
