    I was using the Note 4 watching HD videos with players such as VLC and MX Player, those episodes I watch are MKV format and they played smoothly on the Note 4, I figured since the 950 XL has better specs that it would play them smoothly too but it doesn't!!!, I updated the phone's firmware and still HD video playback lags and stutter, how come this is happening and is anyone experiencing this as well?

    Although I did some initial testing with MKV files, I’ve been mostly playing around with x.265 (i.e. HEVC) videos this week on my Lumia 950XL. In both cases (MKV and MP4 (HEVC) files), I’m watching 1080p videos. The playback for both file types using the default app (Movies % TV) started off a little jagged/with slight stuttering; however, after about 30 seconds, playback for me was smooth (both on screen and through Continuum). All videos are being stored/played back from my microSD card.

    Cheers,
    Justin

    All the 2K and 4K videos from youtube (MS Edge or myTube) are playing fine and smooth.

    Try with another player, UWP Video Player or K-Lite Player can play my MKV files fine.

    if I play the video in normal speed it's fine, it doesn't stutter or anything but because I love watching episodes at a higher speed (AKA time-stretching), that's when it lags, I'm still shocked because I bought the 950 XL with confidence that it'll play smoothly, I read the specs before buying it and its much faster than the Note 4, now I'd like to know how come the Note 4 plays at turbo speed smoothly?, maybe the 950's hardware isn't what it says it is!

    I'll test and let you know tomorrow. However, local playback isn't something i'm concerned with since I use Plex if I want to watch something from my collection and it works fantastic streaming from my home server.

    have you tried with different video players? windows 10 mobile players or WP8,1 players?

    Do you want some help or just bashing windows and trying to sell android?

    I'm copying a 1080p mkv video for testing, if you want some help be patient

    no honestly I'm not bashing, I love Windows and would love some help, I just installed UWP player and its smoothly playing HD but I can't seem to change the video speed, if there's a player other than VLC that allows you to change the speed please recommend it to me.

    Yes, I tried UWP and play it fine, I'll try with another player for change the speed.

    EDIT: I tried with VLC and it is working smooth at 1.5x and 2x, it is a walking dead episode, mkv, at 1080p.

    No, but as I said, vlc is smooth playing my mkv video (up to 2x) on my Lumia 950 XL.

    If your video is stored on external storage (micro sd), move it to the internal storage and try to play it again with vlc.

    actually my videos were stored in the phone's storage and they were stuttering, and I tried from the external storage too.

    I'll download some 2K and 4K videos for try it, it is supposed that the Snapdragon 810 (the one used on L950 XL) can play up to 4K videos with H.264 and H.265 codecs.

    It's possible that the players in question are not coded to leverage the gpu (or other hardware based video acceleration) on the windows platform whereas they might be on android (Note 4). That would explain a lot...especially on higher res videos once the software-based decoding starts to saturate the cpu. Just a theory.

    Try to play the videos using the internal speaker.

    here is a video stuttering on the XL using VLC with high playback speed:


    and here's the same clip on the Note 4:


    this is unacceptable!!, I hope Thomas Nigro fixes this if it's a VLC problem but if it turns out that the XL actually can't handle HD then I'll definitely sell it.
