Will give that a try now.You edit the minidlna.conf file as specified in the wiki. Add the path you want as the example shows. Then restart minidlna.
Regarding that, could I just create a subdirectory within the "drives" folder and call it "sdbMovies", say, and make that the path specified in the .conf file ? (i.e., specify /var/hda/files/drives/sdbMovies). That's what I'm going to attempt.I would caution you about pointing it to such a generic path. It should point to a specific folder like music or movies. There is typically a lot of non-media files in /var/hda/files/drives folder.
Thanks again for all your help
