i am unable to give a step by step tutorial at this time (1am … gotta go sleepy time)
But, 1st Step …try installing a Theme eg. http://community.wd.com/t5/WD-TV-Live-Hub-Themes/ALASKA-RESURFACE-REMIX-LIGHT-DARK/td-p/327445
Here’s a Video Tutorial i found on Youtube on how to install a Theme (_Thanks Tinwarble _)

Once you’ve done that … i will post the code tomorrow (ps. my Theme’s disable the Audio/Subtile info … i don’t like it either)
