Remove v3.2 tags from your mp3 files via MP3tag program. Its a free program. Just set the options (under tools tab) to remove v3.2 tags, APE and only keep v3.1 tags. Then you drag your files to the directory in MP3tag and highlight the files. Then click remove tags. After all tags have been removed click undo changes. All your tags will be restored on the fly with only v3.1 tags being restored. Voila your good to go and all your music should play on the Studio and Rocoo P. I did this for the certain FLAC files that had v3.2 tags embedded in them. After removing these tags and restoring v3.1 tags, all my music plays without any problems (32GB Sandisk Micro SD card and 4 GB of internal memory filled to capacity).
I dun understand this part, ''After all tags have been removed click undo changes.'' Why undo changes? Wont this restore the tags that just been removed?
