As far as I'm aware, the ModuleMediaWriterFileMover will not move recordings created by the nDVR AddOn as they are needed and can be viewed while recording is still ongoing.
The above Module is for moving FLV or MP4 files from the content directory to another location when completed.
This would be used with a StreamType of "live-record" which is what happens when selecting "Options > Record all incoming streams" in the application when editing with Wowza Steaming Engine Manager (WSEM).
Alternatively you can record using the
stream recorder in Wowza Streaming Engine.
