Jamie, looking at those reports it seems it is not only a sound players problem. It is fine that an application that has strict timing issues hints the scheduler. The *application* has to hint the scheduler, not the user. If reports about UI interactivity are true, this means that there's something wrong in the current scheduler though. Besides the player issue. - Davide
