So what is that app for ?
This is a Upnp controller

Particularity ?
Has a unique synchronization system that manage subtitle!!
Haven't found this feature in any other upnp controller. So I decided to do it myself

Does it work on any media player ?
No, I need to have your feedback for an exhaustive list:
Working:
WD TV Live

NOT Working:
Windows media player

May work with any media player that can acces a network share and the read associated subtitles

**** USING GUIDE ****
The only guaranty I've is that it's working with a WD TV Live, so please just don't bother rating the app if it's not working with an other mediaplayer (you can still send me a message so I can add yours to the not working device list)

Step 1 :
Play a video directly on your media player threw a network share (this is important)

Step 2 :
Go in the app configuration and configure your files network share

Step 3 :
-Go to the browsing tab
-Refresh threw properties if necessary)
-Select the same file you are playing on your media player (step 1)

Step 4 :
-Click on the synch button in the Player tab

If everything went well, you are good to go, and play any file you want ... with subtitles!

****** NOTE ******
- RTFM stands for "Read The F*** Manual" :)

- You can open a file from any app (like Mizuu or Es Explorateur).
You just need to do a sync (steps 1 and 4)

- The share must be mounted on your WD, after each reboot it's unmounted and you need to go into the share, so it's get mounted.
To avoid this you can use a custom firmware (go to http://forum.wdlxtv.com/)
