Movies won't open

having trouble with this new device cannot open movie files on my ipad or iphone keeps saying unable play media yet all work fine on pc. have changed them to mp4. m4v and nothing at all. 

The files must be Apple-compatible if you’re using the native app.

Basically:

* h.264 video and AAC audio in an MOV, MP4 or M4V container

* M-JPEG video and PCM audio in an AVI container

How did you change them?

By the way, the MPW device is just storage – it’s not having any problems storing / serving your videos.   But your videos must be playable by the device you are using to access it.

Other apps support more video formats.
