OK, problems this morning. My networking died on one zippered TiVO. All else worked fine at the time. So I ended up fdisking the drive, installing the 6.2 image and running zipper. Put it in, got the green screen "severe error" message. Ran fdisk again, put the image back on without zippering it. Same thing, severe error. What should I assume coupled with the fact that it worked fine except for networking right before I reimaged the drive. I'm assuming if the drive was bad it would have problems in the PC as well. MORE INFO OK, put the recently reimaged drive in my other TiVO using different IDE cable and got same error. Obvious answer you have a bad image, but note: I used two different CD's with different images because I assumed that might be the case when it happened the first time.
