when playing a movie maker mp4 files on my android it will play fine but if I want to watch the a scene again and I back up the video, it will start from the beginning.   I have to wait until the video gets to the point on the timeline that I chose. 

For example:

I watch a video and 60 seconds into the video I want to rewind back to 45 seconds.  If I slide the bar at the bottom back to 45 seconds the movie pauses and the timeline starts over from the beginning.  once 45 seconds has elapses my video starts playing again. 

this happens on two android phones. 

the original move that has not been through movie makers works just fine.  I can move ahead in time or replay moments in the past. 

The same is true for a movie maker mp4 on my pc.  I can move around in time. 

only problem I have is an MP4 from Moviemaker on  my phone. 

I have tried different players and all have the same result. 

Any ideas on what to try. 

Thanks

Dan.
