I managed to do it last week. It took a while.
Yes, check USB on DVR, then format on PC. The pc asked if I wanted to format, so that was easy. Then it worked fine back in the DVR.
I now have a problem, that I lost the software disc. So now I can't playback the footage on the new PC.
Is there a player available that can be down loaded to view this?
None of the std players work
