I copied a m4v video file from my itunes library movie folder on my PC to my new sandisk ixpand video folder.
I plugged the ixpand into my ipad mini IOS v8.2, downloaded and installed the sandisk app.
I am able to see the m4v file, when I tap on it nothing happens. (It does not have the play arrow in the file)
I am able ro select and play the sample video provided by sandisk.
Any suggestions are appreciated
