Just posting this to let you know that Theater Mode is back online. They seem to have corrected the error that occurred when uploading to YouTube too, the error would shave around 80% of the video off giving you a small clip. This was included in the latest patch but I noticed in the patch notes it didn't specifically say that the Theater was up and running only that they corrected the issues of malicious content and stability. Here is a little video I just rendered to test out the feature. It is great to see the Theater is fully functional.
