I recently updated my graphics and audio drivers; they had been more than two years out-of-date. I made no other significant changes to my system, as far as I'm aware. Afterwards, embedded videos failed to load more than a few minutes of buffer at a time. Once the end of that buffer is reached, the video player simply ends the video as though it had reached the end. After the error started, I checked my plug-ins, and only two are out-of-date; Unity Player and Adobe Acrobat. I'm not able to update either of them.
