So you’ve got your Media Browser install all set up with custom icons and a transparent background, to show off your awesome Media Center theme, but now you’ve got a new problem. Those custom folder icons you downloaded show this ugly blue background whenever you hover over them. Well, we better do something about that!
The solution to this problem is actually quite simple. First you’ll need to open up Windows Explorer and navigate to “C:\ProgramData\MediaBrowser\”. If you can’t see the folder that’s probably because it’s hidden by default. You can either unhide the folder using Folder Options or just enter the location in the navigation bar and hit enter.
Once inside you’ll see a number of files, including one named “Styles_DoNotEdit.mcml”. Create a copy of this file in the same directory and rename it “CustomStyles.mcml”. Once you’ve got your copy, open the new “CustomStyles.mcml” in a text editor, notepad works fine. Find the line that reads:
<Color Name="PosterZoomBackground" Color="255, 32, 83, 136"/>
The color values may be different depending on your chosen Media Browser theme. We are going to change those values anyways. Change the color value and set it equal to “Transparent” and save the file.
Media Browser will now pickup that CustomStyles file and apply it to your current Media Browser theme. Easy as that!
Special thanks to Olywa123 on the MediaBrowser.tv forums for explaining the process in detail. This is one of the less documented featured of Media Browser that can make quite a difference.
