I copied all of my ogg music files to DNS-323, then I did the refresh which took a long time.
Then I tried to use my DSM-520 to play them but the files are not showing up.
All other files (jpeg, mp3, avi, mpeg) are showing correctly and work fine.
If I copy the ogg files to a USB flash memory and then plug it into the DSM-520, it plays them fine so there is nothing wrong with the files.
If I access DNS from a linux workstation (as samba share), I can read and play the files.
My guess is that the DNS-323 firmware/software is not considering ogg files as valid music files and it ignores them when it does the refresh and it creates Upnp server database(?).
I am using the latest firmware (1.04)
Any ideas?
