1tb passport connected to WDTV issues

I have about 600gb of data in my new passport drive.

After only watching 2 movies, the screen now goes blank every time I try to play a file.

I try the few buttons on the remote and no reaction until I press eject then the menu comes out again.

Not sure what it is but is there a work around like hard restarting the WDTV or something?

The 1TB passport drive is OK since I can copy files and play movies from it on my computer. It can also stream on my iPad as well.
