A couple of weeks ago I did a new upgrade (from 2016 5-series to 2019 8-series) and I was disappointed to discover that with the more modern iDrive on 8-series the video playback is ALWAYS choppy.
Big or small files, high or low resolution, always choppy.
Changed USB stick to see if there any difference, always choppy.
Restarted iDrive repeatedly, nothing changes.
The videos are in .mp4 format H.264 codec (videos of songs, shows, movies) and I have always watched them without problems on the old series 5.. I don't understand.
