Today, i found some problems with files i previously had no problem playing on my Amazon Fire Stick. On certain videos, i was getting "Unable to direct play as source media has higher h264 level (41) than supported (40)". This is not working on all files. The same files are playing on on my iPhone and web browser with no problem. How do I go about fixing this?
You don't. your amazon stick does not support higher than level 40. It never did. It will need to be transcoded. You can override this setting (on the main plex screen, settings will be in the upper right hand corner) but you are likely to encounter stuttering to complete freeze frames.
