ReadyDLNA rescan in NV+ V2

Try updating to ReadyDLNA 1.0.24: (link to http://www.readynas.com/forum/viewtopic.php?f=76&t=27946) To install on the Dashboard, click Configure, go to the Add-ons tab, click the + button at the far right, browse for the location where you downloaded the add-on, upload the add-on etc. After updating to 1.0.24 if that doesn't fix it this add-on will remove the ReadyDLNA database and thus force the ReadyDLNA database to be rebuilt on the new version: (link to http://rnasguide.com/wp-content/addons/arm/DLNAREBUILDDB_0.1-arm.bin)

I also have a ReadyNAS Duo v2 (as mentioned by ripface elsewhere in this thread) with pre-installed firmware 5.3.3 and had similar problems to that described in this discussion. In my case, I have been able to refresh the ReadyDLNA database successfully using the procedure described by mdgm.
Note that despite installing the ReadyDLNA_1.0.24.3 add-on, I still found that still the only way to refresh the ReadyDLNA database was to run the DLNAREBUILDDB_0.1 utility by adding the pseudo “add-on” DLNAREBUILDDB_0.1-arm.bin each time a refresh was needed.
That is the good news (although I agree with others that a "Refresh" database button is needed on the dashboard).
Unfortunately I then discovered some bad news as summarized by the table below.

Although this issue is arguably better directed at the minidlna project, it is disappointing that the table reveals some inappropriate and unnecessary transcoding. For example, the Samba Client section demonstrates that the ViewSonic VMP74 understands the original ".mp4" format but the DLNA/UPnP Client section indicates that it receives the streamed data from the ReadyDLNA server in a format that the VMP74 doesn't understand. Disappointingly, ReadyDLNA does not quite yet seem to match the DLNA server compatibility of the other NAS brand that I am currently using.
