What can I do about videos that buffer or pause when I'm watching them?
Most lecture recordings give users the option of high-bandwidth and low-bandwidth playback. By default, videos load the high-bandwidth version (720p). However, if you have trouble streaming the video -- it frequently pauses to buffer and has to be restarted -- try switching to the low-bandwidth version.
In the video player, click on the gear icon in the lower-right corner
Select "Quality" and choose a lower bandwidth option
This may be 480p or 360p, depending on the classroom in which the lecture took place.
