Two DVRs, integrating recordings

Hi, is there a way to integrate the recordings made on my Synology Channels DVR into my Mac Mini DVR? I've already set up the Mac DVR (I know, should have backed up and recreated but I didnt for one reson or another) and have recordings which I don't want to lose. Can I just drag and drop the recordings from my Synology into the TV shows file the DVR has created on my Mac?

There is no way to combine DVR databases or to import recordings.

How many recordings are in the new DVR?

Only 8 so far!
