A lowest common denominator solution. Reading http://www.belkin.com/IWCatProductPage.process?Product_Id=543388 I see TWONKY but to get DLNA to function I found it TOO PICKY about file formats. That is, the audio video encoding support was always having me encode the content again.
This is why I ejected DLNA as it stands today and use a media player (Logitech Revue for example.)
I can only guess you have begun this search and didn't figure out that DLNA is not what it seems.
We are having a small problem with de AllShare function of our Samsung HT-D6500 Home Cinema System.
After installing the AllShare application for PC on my laptop I tried to stream mp3-files to the HT-D6500 but it couldn't detect it. The awkward thing is that I can access my PC through that system.
Another awkard thing is that I can stream the files (.mp3/JPEG...) to the TV set (a Samsung UE40EH6030)
Both of the previous named systems are connected to a WiFi-Accespoint (a Belkin N750DB) this accespoint has two USB-ports, on eone of them we've put an NTFS-drive from Freecom 1,5TB. Neither the TV-set nor the Home Cinema set can browse to a file. The only folders which can be accessed are inexisting folders (I hereby mean that these folders don't exist on the external HDD) and strange enough the existing folders can't be displayed/accessed by neither systems.
The most important piece is the N750DB-router, every piece of equipment is connected to this machine either by ethernet-cably or wirelessly. I manually checked every device and they all belong to the same subnet: 192.168.2.XX
