Video Player Problems

Just curious, am I the only one having issues with the video player they use for 90sotv, The End series, etc? I can load HD Youtube videos quickly, and the video player I've seen elsewhere on the site (the one with an orange Verge button--like used here: works fine. It's the one they use most commonly that seems to have difficulty running properly. Even when I set the quality to low, it has a hard time buffering and playing smoothly.
