Important Notice: We are sorry to tell you that Tune4Win M4V Converter Plus for Windows doesn't work properly with iTunes 12.10.2 or later. We are still working hard to find out the final solution and upgrade Tune4Win M4V Converter Plus (Win). If you are in urgent need, we suggest you downgrade iTunes to the previous version V12.9.0.167.

Note: When you are using the old version of iTunes, you need to re-download the movies with the old iTunes, too. The new version of iTunes uses a different type of encryption technology. And remember to de-authorize your iTunes and re-authorize it all over.
