Can I make a back up of the recordings I have saved to my DVR? I noticed what looks to be a usb plug on my DVR I just do not know if it can be used to copy the content to a computer hard drive for compression and archiving. My DVR is a Scientific Atlanta Explorer 8240HDC, any help would be appreciated.
No. the recordings are married to the box.
even if you pulled the hdd and put on PC, they wouldn't play.
