I've just bought WD TV Live and My Passport SE.
Copied a lot of movies to the HD, and when plugged it to the WD TV, it scans the unity and after this process show the message "Unable to create media library. Pelase check your storage setting". I've already tried to remove the drive security password, but it didn't work either.
When plugged to the PC, I can see the .wdtv folder in drive's root directory, which is the same directory wd tv created in my pen drive, and seems to be the media library database.
WD TV is updated to the last version of firmware.
Thanks in advance.
