Any program that removes album art from the id3-tag will work!
Mediamonkey for example will do it while it's transferring/syncing songs to your MEIZU - you just have to check "Remove images from tags if larger than x KB" in the Sync-options (Device Profile).
For x you should write "1" KB so every album art will be erased while the transferring-process.
You can also force Mediamonkey to automatically copy Album Art as an image to the songs directory instead (named <ALBUM>.jpg). Finally syncing is done with one single klick - settings have to be applied only for the first time.
For me now this problem is completely solved - it's HISTORY!!! Yeah!
Now this Player is nearly flawless IMHO and my SAMSUNG P2 is on sale!
Thanks to everybody in this community for the hint on id3-tag-album-Art. Very helpful indeed!
However, the stuttering-bug is a very annoying bug and shouldn't exist in the first place.
But in the end this simple workaround is just a minor nuisance to solve this rather awkward problem.
BTW: I highly recommend MediaMonkey 3.0 to everyone to organize/sync your music!
