Hello Powrus. I stream through my DVD player which is connected wirelessly to my modem/router that connects to my PC. It uses the functionality of DLNA (Digital Living Network Alliance) built into Windows.
In Windows, go to Control Panel/Network and Sharing/Change Advanced Sharing Settings. You'll be advanced to the screen where you can set sharing settings for: Private/Guests or Public/All Networks.
You should turn-on access in all these sections. When you get to the All Networks, you'll see Media Streaming under which there will be blue text that says, "Choose Media Streaming Options..." Click on that.
The next page will display a box that reads "Turn on Media Streaming". The next page will show all devices in your system. Make sure to Allow these devices and then click on Customize on your device.
On the Customize page you'll want to check "Make all media available to this device".
After having done that, you will be able to stream your music, photos, etc. to you TV.
Best of luck.
