Video Player problems with Chrome.

Hi, I'm experiencing various problems with the video player, videos either take ages to load and keep buffering or they just stop in the middle and can't be recovered. Also, would be nice to have a "replay" button available. I'm using Chrome but these problems don't seem to occur on other sites like Youtube, Twitch et similia. If this isn't just my problem please fix it, it's becoming a little frustrating.
