Re: Youtube video downloaded as mp4 is an unsupported media
If you search on the term 'YouTube' here on our forum you will find very many threads with this issue.
This is a general issue at this moment. We have reported this to our developers. You can for now (since you have Mini2) use YouTube XL, this should work. You can use full screen by pressing the 'zoom' button in YouTube XL.
The downloaded movies you have from YouTube most likely has a format settings called: VP6. Some of the YouTube video files has this setting and our Realtek products don't support this. You can confirm this by getting a free software that is called mediainfo and check the files. Let me know if they would not have VP6 as format setting
