    and I'm getting a black flashing rectangle in the lower right of the video when I play it with Media Player Classic Home Cinema. If I expand the view to full screen, the rectangle moves to the centre. In Options, Playback, Output, I've got DirectShow Video set to Enhanced Video Renderer (custom presenter) Can anyone tell me why I'm getting a black flashing rectangle?

  2. What about other media players?

    It plays absolutely fine in Windows Media Player, and in Firefox's own internal player, somewhat stickily in PotPlayer, and VERY stickily in GOM Player. MPC-HC is my preferred player though so I'd like to see if there's a way to get rid of the black rectangle.

  4. Ok, so we know the problem isn't in the video file. I don't see anything obvious about the file properties that would cause such a problem.

    As a test, have you tried different output devices in MPCHC? Try remuxing to MKV and see if the problem persists.

    You're gonna have to tell me how to do that, I'm afraid.

    I don't know what's happened but suddenly there's no black rectangle. I don't know what caused it, I don't know what made it disappear, I didn't change anything, so I'm a little worried that it indicates something wrong with my computer.

  8. Oh god almighty, now it's back again! But I'm not doing anything! What the hell is wrong?

  9. Now it's gone again. This is driving me up the wall. I'm not doing anything different. What is with this flickering black rectangle?

  10. Have you rebooted?

    A few times today. I'm noticing though that this black rectangle thing isn't happening with any other videos. Just this one. But you said you could see nothing wrong in the mediainfo to indicate why.

  12. Just because I didn't see anything unusual doesn't mean there isn't something wrong with the video. MediaInfo only shows what the headers indicate. Did you try remuxing? Maybe just a remux or a remux to another container will fix the problem. I'd try remuxing to MKV with MkvToolnix first.

    Yep, tried that. Didn't work. Same problem.
