I am using the WD TV Live and when I access the files from my NAS It lists only in one column. I have seen some You Tube videos on WD TV and they show the files in 2 columns.
Please advise how I can set the unit to show 2 columns of file names.
This is up to how you access your content (Network shares vs. media servers). Media servers in particular are able to display different layouts unable to be controlled by the media player itself.
