mkv not playing on my Mac anymore

[rozner]

Hi,

I've been playing mkv's just fine on my Mac for a while, they're 720p and I think using h.264. I'm not sure what happened but I keep getting this error:

ffmpeg: more than 5 seconds of late video -> dropping frame (computer too slow ?)

My Mac is a MacBook Pro 2.4 ghz (intel) and normally I can play these files while running Windows in VMWare amongst other things. At first I thought it was just the file, but I tried some older ones that I know I've watched perfectly and they all screw up now with this error. I don't really understand what can be causing this, I've tried rebooting and all that. If I look at activity monitor it's barely even using the CPU, like 10% maybe. Thanks for any help with this.

have you tried deleting VLC's pref files. unless you have been playing them in windows only before. i dont have any issues with VLC playing anything in a .mkv on my P4 2.8ghz PC running XP pro. but my Mac can not play a low quality divx video in a .mkv container. if i use MPlayer OS X or Niceplayer i can play some videos in .mkv fine but not HD content.

i think everyone with a Mac can not play HD content in a .mkv even on a new intel Mac using VLC in OS X.
BTW try using a older version of VLC to see if its something with the newer version on your system.

i have never been able to use VLC in OS X to play videos in a .mkv container. i have to always use Mplayer OS X or Niceplayer to do that. VLC dont handle anything in a .mkv well
