You may be familiar with this but in case otherwise -
USB memory sticks need to be formatted with a File system. There are quite a few options and it may be that the Vu+ box does not like all possibilities.
Very briefly - The most compatible is FAT32 however there is an absolute file size limit of 4GB which may be a problem with video files if you use high quality settings. It's replacement exFAT has no such limit. NTFS is the Windows native file system but there could be compatibility issues with Linux (likely the basis of Vu+).
