I have a sd-dvr80 hughes Directivo DVR which was have loved for the past 8 years with NO problems. However on Tuesday I noticed a few times on a playback the sound cut out. I thought it was just the recording till it happened in another show. Then I jumped back to the spot again and this time the sound played so I knew it was not the recording. I also noticed the menus were slow and sluggish. I rebooted and everything was fine. Till today (Sat) and I noticed the same thing. Rebooted again and this time fine until only a few hours later. Is my Hard drive going bad??? Is it the unit? How can I tell? What are my options? Buy a new HD and buy an image it? Buy a pre-imaged HD from somewhere online? and just pop these in? Will that fix it and if so from where? Is the unit bad? Should I buy a new one on ebay? Can I even still activate these old ones? Please help!
