ID3 2.4 can cause various MP3 players, especially on vehicles or even computers, not to play or at least not to display the ID3 tags.
In many cases though, since ID3 2.4 is much different than version 2.3, it will cause some players, especially in cars like Lexus not to play. Even on the computer, you may notice if you check the properties of the MP3 that it won't open or show any details (eg. frequency, bitrate and ID3 tags).
One symptom of this in a vehicle (eg. Leuxs,........
A very common use case is that you don't want to waste time using a video editor that requires you to open it up and manually import the video clip and audio clip, then manually delete the old audio track and import the video and new audio.

When things go wrong your video is basically unplayable or the first video plays fine and then freezes when moving on to the next. Generally if both videos weren't produced with the exact 100% same settings you will have issues. You can try the basic concat but it often won't work right.
Solution for me:
My example uses 3 videos in total so "n=3" and a=1 to include audio.

In my case I already copied the VIDEO_TS folder to my hard drive.
Here is the command for mencoder:
mencoder -dvd-device "myvideobackup/VIDEO_TS" dvd:// -ovc xvid -oac mp3lame -lameopts cbr:br=128 -xvidencopts pass=2:bitrate=-700000 -o myvideobackup.avi
Replace "-dvd-device myvideobackup/VIDEO_TS" with the location of your backup files or the /dev device of your DVD drive.
The -o myvideobackup.avi is of course the name o........
