Please be patient. Our Windows expert on this topic is on vacation. In the meantime you could try different render methods and sw decoding. Post your observations.

Update: decoding set to auto is not stuttering as long as DXVA2 is disabled, so we already know what is the culprit here.

ATI Radeon R7 240
Kodi 17 latest Nightly.
I have a weird feeling that the AMD Drivers plus Anniversary Update is causing that hickups.
Even more weirdness. After a restart DXVA2 is working fine for about 10 seconds then the stutter fest begins and it's getting worse the longer I keep playing the videos.
Buffer overflow in the driver's code?

I have the same problem. AMD R290. Latest driver.
The issue started with win10 update, the issue is most visible for live tv. Its pretty much unwatchable.

I can resolve the issue by turning adjust refresh rate to off or by leaving on and turning hardware acceleration off.

Are you guys trying to play x265/hevc encoded movies? If so, then I would say your video card doesn't support it like mine (Nvidia GTX 650).

Also having these issues on 17 (slight stutter and black screen on exit) since the big ms update, had it across 2 systems both with win 10 anniversary update but only in full screen mode, if i use full screen windowed its fine.
had it happen on a gtx 980 and a gtx 1080 across z77 and z97 across multiple drivers.
16.1 full screen works as it should.

You tried dropping back to double buffered? I get buffering on live streams with triple that i dont get using double. Worth a try.

Syncing display to video option seems to resolve the issue for me. I will see if I can re enable hardware decoding.

I'm having a similar issue. Interestingly not on Windows 10 but on Ubuntu 14.04 with AMD fglrx 15.302. I didn't update for quite some time and did it last week (Kodi 17 nightly). Since then, some videos are stuttering in the described manner. It happens for different Codecs/Containers and different frame rates. I can't seem to find any similarity between the affected files.
One observation I have made is that the stuttering disappears, if some OSD is visible. E.g. if I show the video information or progress bar. It goes back to stuttering as soon as the OSD disappears. Maybe those affected could confirm that behavior.
