DLNA not showing all folders on easyshare network

[goldstubstar85]

what are the common errors with using DLNA or UPNP?
I have a Netgear easyshare DSL router with a 2TB USB plugged into it.
I have a digital box & PS3 that have the ability to access a network via DLNA but neither of them are accessing all the folders properly. I have 3 folders:

Music
Pictures
Video

the problem I have is that when accessing it only shows visible the music folder & a small portion of the sub folders! A friend of mine is also experiencing the same problem & I have now used 3 different devises to access the data over the network & all 3 are doing the exact same thing in only showing a small portion of the folders (& files) that I know are actually there

DOes anyone know how to fix?
