I don't know where you get the so-called file information.   The string "storage/emulated/0/Movies" is not a valid path name.  You might at least need to add the root prefix.  So, please try

     Movie:///storage/emulated/0/Movies/filename.mp4 

However,  some devices may have the file system mounted in special way or use some soft-link to make things more complicated.  So, the MobiControl script engine may not be able to locate your file properly with "/storage/emulated/0/Movies/filename.mp4".  It's easy to test out.  Just send a script command to try out a copy operation to see if you get a duplicate copy in the copy destination.  If successful, you have nailed down the right way to reference your source file on your device.  No one else can do this test for you.

Hello,

without lockdown, can you view the video ?

Also, which device do you use and which version on android do you use ?

thanks

Using 

     Movie://sourcefolder/filename.mp4

is virtually no different from using

     file://sourcefolder/filename.mp4

to specify an MP4 video file to be played.

If you have problem, either the pathname before the suffix "filename.mp4" has not be properly defined to locate the file, or your device does not have any default video player app  bind to file with extension .mp4 for playback.

I'm trying to play it from the device's internal storage. The file could be played without the lockdown, so it has to have a default player.

The file info says it is located in "storage/emulated/0/Movies"

so the correct line would be Movie://storage/emulated/0/Movies/filename.mp4 right?
