I am making sure that I'm using the supported formats for the Vita, but every video I always get this message, "This file is not compatible with the PS Vita system." Is anyone else having this issue? If anyone knows how to fix the problem, please give me a step by step tutorial. I can watch mp4 videos on my PS3, but mp4 videos just don't want to play anymore. Thank you so much for your help.
The Freemake Video Converter converts movies to just about any format you like. It's freeware. I download YouTube videos using their video downloader. If you install them, I opt out of installing any other thing they might throw at you, such as real player, Google add-on, etc.
