Hey it's not in v1.11 but in 1.15 (I might update it here soon) you can do it in the following way:
Vids need to be placed in a proper folder structure, you need a 'videos' folder, then the following subfolders by theme 'normal' or 'sexy' or 'workout'. Put your videos in any of these folders.
Folder structure:
videos
| normal
| sexy
| workout
Videos need to be in the .ogv format (you can find free websites that convert videos) and try to keep them low res (640x360 is fine) for the sake of performance. Audio cannot be changed, that's an engine limitation.
