Some videos can be played back while others of the same type cannot be played.

Symptoms

Some videos can be played back while others of the same type cannot be played.

Cause

.FLV, .3GP, .AVI, .MKV and .MKV are just media containers. They are all different and require different decoders in order to play them back. Acronis Access relies entirely on the codecs that are built-in on the device. Different device manufacturers may ship different codec packages resulting in some devices being unable to play some video files.

Solution

Using a media player app that has the necessary codecs will allow you to play the video file.
