    .mkv (and .mp4 for that matter) are container formats. Within the container a variety of possible codecs could be used for the video and audio streams. Without analysing the precise construction of this particular .mkv it's impossible to say, but it does sound like something about it was incompatible with WMP.

    Conversion would have been my next suggestion, at least you now have it in a form that you can play. I've been converting to .mkv in order to try and reproduce your problem, but they all play fine in WMP. It's a mystery we'll probably never solve...

    I used a trial version of Internet Download Manager to download it from youtube. the music video was this one, and idm caught it from youtube as a .mkv file at 360p quality. even when I tried downloading it at 480p quality with idm, the problem persists

    Thank you for providing the details, I've analysed the video in question using FFMpeg.

    The 360p original uses the webm container format. The video/audio formats are vp8/vorbis
    Code:
    Metadata:
        encoder         : Google
       Duration: 00:04:17.72, start: 0.000000, bitrate: 837 kb/s
        Stream #0:0: Video: vp8, yuv420p, 636x360, SAR 1:1 DAR 53:30, 23.98 fps, 23.98 tbr, 1k tbn, 1k tbc (default)
        Stream #0:1: Audio: vorbis, 44100 Hz, stereo, fltp (default)
    Windows doesn't have a native vorbis codec, so I converted the audio to aac, leaving the video 'as-is' and saved to a .mkv.
    Stream mapping:
    Stream #0:0 -> #0:0 (copy)
    Stream #0:1 -> #0:1 (vorbis (native) -> aac (libvo_aacenc))
    The resulting .mkv plays perfectly in WMP with none of the problems you describe, so the original video itself isn't the cause of the troubles.

    I then tested Download Manager 6.31 on the 360p video. I'm not sure how you got it to output to a .mkv file, for me it created a .mp4 with no options I could find to change that. The .mp4 it created also played perfectly in WMP. Both the audio and video were recoded during the download.
    Code:

        Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, bt709), 636x360 [SAR 1:1 DAR 53:30], 503 kb/s, 23.98 fps, 23.98 tbr, 90k tbn, 47.95 tbc (default)

        Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 125 kb/s (default)

          handler_name    : SoundHandler
    I've done these tests with WMP on two machines, neither of which have additional codecs installed bar those supplied with Windows itself. One was a 32-bit OS, the other 64-bit. TBH, I'm at a loss trying to recreate your problem, it all works fine for me.
