Has there been a solution found for this problem as I have the same situation with the same equipment.
The TV can see the drive and the files on it, pictures, music (MP3) and video (AVI). I can see the pictures through the TV but when trying to launch either the music or video files I get unknown file format. But when the files are accessed from a laptop that is DLNA compliant I can see and hear them on the TV.
I have upgraded the firmware of my Linkstation to 1.21 and I have also performed the steps given previously but I still no luck.
My network setup is the same as previousl mentioned.
I have no problems with the the Linkstation through either a laptop, XBox 360 or PS3 but I dont want to have these on as i should be able to access the files through the TV.
Is there anything that can be done to sort this out?
Greatly appreciated.
