Here is my problem. I have some education videos I have downloaded, legally, and I what my wife to see in in the bedroom. We have a TV there with a Roku. So I want to broadcast the videos from my PC to the Roku in the bedroom.
Any help welcome!

You can use Windows Media Player on your PC as a DLNA SERVER (see your first link). Install the Roku Media Player app on your Roku and it should be able to find the DLNA server and play videos from it.

Also, if your PC supports Miracast, you can enable it on the Roku and send the output from your PC to the Roku. GOOGLE Miracast on Roku for how to enable.

Personally, I use Plex media server coupled with the Plrx app on my Roku.
