v17 DVD playback intermittently slowing down then resuming normal speed
#1
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.

so, i think there is a problem with UI of the player probable memory leak, because when the movie starts to slow down (after usually every 10/15 minutes)
if i try to show the player controls (paure rewind etc..) (also without pause movie), the movie immediately begins to return fluid without problems.

My system is a dedicated HT computer:
Intel Core 2 Duo E6300
2 gb ram
Windows 10 Pro
Kodi Krypton 17.0 RC3
And play movie always throught DLNA with USB Wi-Fi AC 1600

NOTE: i don't have problem to play MKV at 1080P of 10GB....

It still occurred with RC3 but starting completely from scratch seemed to have fixed it.

Well, at least if I disable "Allow hardware acceleration - DXVA2" on the laptop but the desktop works fine with it enabled.
