There’s pre-built executables. You probably want pms-1.90.1-setup-full-x64.exe.
Just install it, run it, look at its settings for what drives/folders you want to share. The “PS3 Media Server” will show up on your TV if it has a uPnP/DLNA app (they sometimes have different names due to licensing. My LG TV has an app called “SmartShare” - but it is just this).
For your tablet/phone I use BubbleUPnP - free app. It will let you see all media servers, you choose what you want to play and where you want to play it - all the DLNA renderers (smart TV’s). You may want to setup “transcoding” settings, which will convert certain formats to that that your TV codecs can play (typically H.264). To play video on the tablet/phone you’ll need another video player, I use “MX Player” - another free app.
Your router should be more than fast enough, I assume your devices/TV’s have at least 802.11n.
Thanks much!
