If you are a windows user you can also use my Winhelper Tool - see
viewtopic.php?f=17&t=12136. This tool will monitor shared folders and will automatically refresh the Serviio library after the file changes.
Compared to Serviio 1.5 it comes at a cost though - when a file is being downloaded the OS sends multiple events to the WinHelper Tool. Therefore on receiving a change event I have set WinHelper to wait for a minute to see if another change event occurs (representing a file that is progressively being written). So the upshot is the library refresh isn't [near] instantaneous (as it is in Serviio Version 1.5) as it waits until a minute of no further file updates before doing a Force Refresh of the library. It also uses Force Refresh which seems slower than the new delta scanner in version 1.5.
When Serviio 1.5 is released it will provide near instantaneous library refreshes for Win users, but it wont refresh for progressively downloaded files (eg. torrents). I have written a small program that can be run after your file is download that will perform a Force Refresh automatically - I have added this to my bit torrent client to run after download is complete, and that has fixed this issue. I'll make this torrent client add-on available when 1.5 is released.

I have never tested this (you must have a slow download?), and agree with the above - could produce wierd outcomes. WinHelper should improve this as it will refresh periodically throughout a file download. The new version, even with my add-on won't (as there will only be an automatic refresh when the file is added/started, triggered by Serviio, and one by my add-on at the end of the download).
