In the thread aforementioned MP3 scores were reduced to avoid false
positives, so please try to lower again MP3 scores:

In function mp3_read_probe() in libavformat/mp3.c instead of ...

else if(max_frames>=1) return 1;

use ...

else if(max_frames>1) return 1;

If that works I'll send a proper patch to the list.
