I don't even know if it is the hard drive, the phone techs don't do much more than just send me a new one. All I know is at some point every 622 I have had starts jumping to 'LIVE' while watching a show that is still recording or jumps to the end (or permanently freezes) when watching the same program after the recording is done. When I watch the same shows off the external drive I have NO problems at all. Does e* just use really bad hard drives in their DVRs? Are others having this issue? TIA
