Kodi provides a built in characteristic called Kodi Buffering. This feature was introduced by Kodi staff to their paid members. You can try to allow it but do not proceed with the expectation that it will work as predicted, especially if you are on a low tempo internet connection. I just tried using the buffering characteristic and this seemed to do the job but it really is better this website if you use this kind of feature to show the video and do not attempt to see the video at all.
