I would not have thought it was possible for a live video feed to go that bad. In addition to all the issues you mentioned, towards the end I had the video feed randomly flip between live content and content from an hour prior. It also froze for a while when the words "Image Stabilization" came on screen, a little too much stabilization!
Bandwidth issues I could almost forgive, or at least understand. But the technical issues they were so technically awful it seemed like they hired a first grade class to do AV and fed them jello shots beforehand.
Hope they can assemble a watchable video for viewing later, it was so bad you almost have to wonder if Chinese is not permanently embedded over Cook's voice in the master recording.
