There are three known and confirmed bugs with YouTube. They include not being able to save changes being made to videos, and issues playing and sharing videos in YouTube Groups and Orkut. Here are the three threads created by Liz from the YouTube team:
We've seen a lot of reports from you indicating that on the "Save changes" button isn't appearing for you on the edit video page for your uploads (my_videos).
I've reported this situation to our team and they're working on a fix so that you're able to save the edits you make to your videos again without running into this issue.
We've seen many of you report that videos you've submitted to a YouTube Group are not playing on the page. A grey box appears in place of where the video should appear in the player and sometimes an error message is displayed stating that the video is no longer available. The video is in fact still available (from the uploader's channel and in search), but its just showing as unavailalbe in the Group setting.
This situation has been reported to our Team here in San Bruno, and our engineers are currently investigating the issue and working on a fix.
Just wanted to let you know that our Team is aware of the issue with sharing YouTube videos to Orkut. Many of you have reported here in the forum that when sharing one of your uploads to YouTube on Orkut, Orkut produces an error message saying that your video doesn't exist / isn't found. Ah!
I've reported this to our engineers and they're currently working with the folks over at Orkut to try and resolve the situation. A big thanks to you all for letting us know about this issue, and we really appreciate your patience as we're working on a fix. Hopefully you should be able to enjoy YouTube videos on Orkut soon.
So those are the three issues.
