I have a similar problem. I have ultraviolet movies already redeemed in flixster, but I can only play them in the flixster app. I want to move them and be able to play them in other apps, but I can't. When I use video download capture (evaluation version) I get a large mp4 file that won't play in anything either and some apps see it as only having an audio stream. Is there any way to convert my flixster/uv movies to usable mp4s?
I realized I left some information out. I have downloaded the movvies in the flixster app on my phone and desktop computer. My phone is a samsung Galaxy S5 running lollipop and has a 64gb sd card. I tried the Flixster video app as well.
