Both devices can be seen by my Mede8er MED600X3D and stream without issues
I have my files stored under a public folder on each.
Windows File system is enabled on both under Network Settings.
I can browse folders and files either buy using My_Shortcuts and manually typing in the IP address of the NAS with guest and blank password, or Browse under Network -->WORKGROUP without any login information being required. Either process allows me to add a folder shortcut link to the Favorites Screen without issues.
Streaming of large files (>20gb) has not caused any issues.
Network configuration is via a gigabit switch and CAT-6 cabling between the NAS and Mede8er.
