Compiling media files

I USB synced about 250gb from an external hard drive to my media live hub. Even though it has downloaded the content it seems to be taking an extremely long time compiling files on the top notification bar even though I can play all my files is this normal?

Depending of how much data you have it might take some time. How long is taking to compile the media?

… and which step is taking long?   The “Compiling Media Library…”  or “Getting Content Info…” ?

Lesson 1) Not all jpg files can be displayed by the wdtv live hub.

Just had to be a bit patient left it to run overnight. All synced and fine now, thanks.
