Have had this happen twice now. All of a sudden while watching 2nd tv with the H24 non-DVR, a message pops up to the effect that the H24 has disconnected from the HR24-500 DVR and that recordings are not available. Sure enough, upon checking, the recordings are not available on the H24. But after a while this malfunction corrects itself and all is ok. Happened for the second time this morning. Have not yet gone back today to see if it has again corrected itself. Does anyone have any idea what is going on here?
