Oh noes, something doesn’t play right! How do I report it?

Providing detailed info when you encounter a playback issue will help us investigate (and resolve!) the issue quickly, so things improve for everyone.

• Test whether you see the same playback problem with the old player (see the information on switching back below)
• Reproduce the playback issue with the NEW player
• Grab logs from your app (iOS App Logs or Apple TV App Logs)
• Save the “XML file” for the library item you tried to play (XML File Information )
• If possible, create a small sample file (Generating Sample Files) of the video causing the issue, verify that the sample still causes the issue, and then upload that sample to somewhere such as Dropbox or Google Drive
• Report your issue in our iOS Beta or Apple TV Beta forums with details about what exactly you experienced. Be sure to attach your logs and “XML file” and link to the sample file.
