Adobe has received reports that desktop AIR 3.5 users of BBC iPlayer and Digital Theatre Desktop Player are no longer able to play or download video after upgrading from AIR 3.4 or earlier. Specifically, the user will attempt to play the video and will get a black video window or will fail to successfully download videos. Adobe is working on a permanent resolution for the issue in AIR 3.5. In parallel, Adobe is working closely with the BBC and Digital Theatre to offer support and investigate interim resolutions. We will publish an update as soon as we have released the fix.
In the meantime, the work-around for affected users is to migrate back to AIR 3.4. The following link provides instructions for determining the version of AIR currently installed on your machine. If you believe you may be experiencing a video playback problem caused by migrating to AIR 3.5, your video service should be able to tell you whether they believe going back to AIR 3.4 or earlier will resolve the problem. If instructed to do so, the following steps here can help you uninstall your current version and locate and install a specific AIR version for installation on your Windows or Mac PC.
Please feel free to report your issue or reproducible steps here and we will alert you once a fix has been put in place. We sincerely apologize for any inconvenience and thank you for your continued support.
