Usually, we transfer events from the EHD back to the receiver to watch since the resume wasn't working before the latest software download. Now that the resume is working, we watched something directly from EHD (WD Essentials 500gb) while the receiver was recording something else. When we finished watching and hit delete, our receiver rebooted. Luckily, what was recording was no big deal and could be rerecorded later. Have had no other problems since getting the EHD during the Olympics and have never had our 622 spontaneously reboot. Has anyone else had this reboot thing happen?
