Advertisements Hi, I have a Tivo Premiere XL Series 4 with WD 1TB External AV Expander Drive attached. I started having issues with recordings freezing or receiving the below error message when trying to play a recorded program that I know was recorded. Error playing a recording "The Tivo box was not able to record this program because there was no video signal on the channel. You may have been trying to record on a channel that you don't receive." I know that there was a signal on the channel that was being recorded because I was also watching the program as it was being recording. I ran the Tivo hard-drive S.M.A.R.T. test and received fail 7 on the Secondary Short test, Conveyance test and Extended test. Does this indicated that the external drive is bad? Could the error message indicate a possible cable card or tuning adapter problem? Any help would be appreciated.
