This happens on every DVD, while playing the video will at regular intervals appear to slow down or lag then resume normal playback speed (audio doesn’t seem to be affected by this). It is not random, at any given time in a movie it will always happen at those times in that movie. The lag lasts a couple of seconds or so then play normally for maybe 10 seconds, and repeat.
This issue doesn’t appear at all in 16.1. For those analyzing the log, it happens on the same movie from the hard drive. I have an external TV hooked up, happens on either display, or without the TV using the laptop’s monitor, or full screen or windowed. Altering the display buffer setting between 3 and 2 had no effect. The computer is more than capable of playing DVDs and Blu-rays, and there is nothing else using the CPU or memory besides the OS.
