iTunes channel NOT SUPPORTED!!!
If you ( like me ) use your iTunes library with PMS this will be a big dissapointment for you. In version 4.0 iTunes channel is not supported (which means no Audio or Video).
Since developers decided not inform us of such a major change ( disadvantage ) someone had to do that.
Unless you are not using iTunes channel DO NOT UPDATE!!!
