I just upgraded my dead Tivo HD with a Premiere 4. I have been using a WD DVR Expander for a few years now and wanted to move it to my new Premiere 4. I transferred the shows I could from the old box to the new, and now I have unhooked the DVR Expander. I read that all I should have to do is hook it up to the Premiere, and it should recognize it and format it, but that didn't work. Is there something else I need to do to clear off the DVR Expander and have the new Tivo format and recognize it? Suggestions much appreciated. BTW, I read about a kickstart 54, but couldn't get it to work. If I am able to get the kickstart to work, will that remove the recordings I transferred to the new Premiere? Thanks for the help.
