Another way of sharing files from your computer to your Samsung aside from my posts here and here is by using Vuze.
Vuze can be used to stream files to Samsung LED TVs instead of using Samsung PC Share Manager. With Vuze you can easily share torrent downloads to your TV using the same sharing technology of DLNA. The files you can share are not limited to the torrents you have downloaded. You can also share photos, music, and videos if it is saved from your hard drive,
flash drive or other storage devices.
This way of sharing files to your Samsung LED TV is easier compared to using Samsung PC Share Manager. Vuze automatically lists the Samsung TV's or devices that it finds in your home network.
Just by Drag and Drop you can copy the media you want to share from the device's library in Vuze. In the above image, you can drop the files in Samsung DTV DMR under the Devices category. As you drag the file and hover it over the Samsung TV, you will see a small plus (+) sign indicating that the file will be added to the device's library.
Finally, on your Samsung TV remote press Source. The source list should show the Vuze DLNA Server. Select it, and it will display the files you have on the shared folder, whether it is Photo, Music or Movie.
