My DirecTV DVR is beginning to go flaky. I can return it to DirecTV and they will give me a new one, but the problem is that I will lose all of the HDD contents. I just want a way to back up the files (even if they can't be played in their backed up condition) so I can later load them right back into the same type of DVR where that CAN be played. There is about 150 hours of programming on the HDD, so simply playing one show at a time and recording the analog output is not really an option. Any suggestions?
