UE46D6500 conecting to a NAS?

[nikolav]

Hi!
I have that TV with 001018 firmware (the latest automatically updated on first setup)
Is there a way to access a NAS (D-Link DNS-320) directly via IP and not with it's UPNP function?
I red that this firmware I can't use SamyGo, but can I use just some app. without reflashing anything?
The reason I need that is that right now with the UPNP stream the TV can't reed MKV files and the TV doesn't see the subtitles.
