Maybe some of you have encountered the following problem and can suggest a solution. I am using a Mac laptop. It is great for work. And for watching a quick video on YouTube it's fine too. But when it comes to videos in MP4 format, my player quite often has playback errors. I don't fully understand what this malfunction of playback of this particular video format is connected with. I understand exactly what prevents me from enjoying watching content in the most common MP4 format on Mac. So if you have found a solution to this problem, please share.
