good info......my dvr is a SA explorer 8300

i'm seeing options to add an external hard drive for more storage from other forums....but don't seem to be able to control which hd the recorded show goes to (it ping-pongs to whichever hd has more storage space available).....so if my dvr dies (which has happened in the past) there is no way to save my saved content, as when you conect the external hd to the new dvr it will format the external drive.....defeating the porpose.
looks like a dvd recorder is in my future unless another solution is out there.....
transfering content to a pc would be sweet though....
