Actually ignore my post regarding the Harmony remote. I have realized it is going to be overkill to use just for Plex - I prefer using the remotes for each device (even tho it takes up more space). So am going to return the remote and hopefully find one that works. Currently using the VideoMate K300 which is perfect for what I want but the range is pathetic - you literally have to be 30cm away from the receiver to get it to work which is extremely frustrating and also the fact that it is linked with Windows Media Player, if you accidentally press the big green windows button, it closes Plex and open Media Player which I don't want.
So could anyone recommend a remote that they are using and can guarantee works well?
