Make the TV the ONLY WiFi device in the house. This will give it the full bandwidth and see if it's that.
I have a 58" Samsung Plasma TV and just purchased the dongle so I could see my videos, pictures and hear music on the TV. I am having the following problems:
1) On home recorded HD videos it will only play a few seconds before it has to load again. It does this continuously unless I manually stop it.
2) I returns me to MEDIA when I want to choose music from my main PC which is DLNA (as are all). I have almost 4,000 tunes.
3) It is finicky about picture folders.
It does see all the PC's as sources of DLNA.
Since there seems to be very little documentation about how the TV and the Dongle work together with each other and other devices I am totally in the dark. Also, I am considering buying a Samsung Wireless Bluray player and I can't tell if I should just hook the dongle up to the player OR I need to buy a Samsung player with built in dongle.
