We have been running recorded webinars for a few months, and each time there are attendees who comment that the video was buffering the entire time every few seconds. I've tested it on my PC, on different browsers, and it's not my internet connection. These same videos uploaded on YouTube have no issues. What could be the issue? I have a feeling that GTW can't playback the quality of video we have at a good speed, or the connection from our attendees to the site is not good (majority of us are in Hawaii).
