To use DLNA all you need is to make sure your Bravia Television is on the same network as your computer and the 3rd party DLNA streaming device ( in this instance your roku). If you require assistance linking your 3rd party streaming device to your PC, please contact the manufacturer of the device directly (roku).
for more on DLNA please review our DLNA setup and FAQ page here:
For further assistance, we kindly recommend visiting our Sony Global Website for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/. Due to proximity, they are in a better position to respond to your questions or concerns.
