Well, it *was* working, so now I have to look into what's gone wrong.
Is your HD a network-attached HD, by any chance, on which you have the ability to turn on FTP? That's how I'm doing it -- the 5009 allows for motion detect triggered video to an FTP location, so I just ftp it to my network drive that way.
I can give more details once I find out what failed, IF you can do FTP...
