For the past few weeks, my guide data would slowly change to nearly every channel showing "To Be Announced". From other posts on that topic, I ran the Clear Guide Data and it worked. A few days later I started seeing more To Be Announced entries and ran it again and it's been fine for a couple weeks. Once again it started happening and I ran Clear Guide Data, but now my Premiere is stuck on the boot process. I tried using Kickstart codes, but they don't seem to do anything. I pause at the yellow flash and it stays solid, I type in a 2 digit code like 59 and the green and yellow lights flash alternating then stop, and the TiVo continues to boot into Clearing Guide Data. I suspected it may have been a hard drive issue, so I replaced the stock 500GB with a 2TB WD Red drive. I boot it up and it goes straight back to Clearing Guide Data. What more can I do??
