MP4 video no longer works in 4.18 for Android

Finally 4.18.2 is here but still the same problem. New proyect in 4.18.2, third person & configured for mobile (android). New default level with only 3 planes in scene. I downloaded sample video from
link text

and follow the steps for create file media source,media player & media texture, etc and everything works perfect but when I package in ASTC and try to play it, videos are invisible but the sound is working and the most stranger thing is when I shoot the weapon from the third person and the ball (proyectile) hit where the planes would be then I see the plane in red color, no video. What can I do?
