I've been catching up on some naruto shippuden recently. All the files I have are in .MKV format, and since WMP doesn't recognise the subs on the video, I'm using the Classic Player. Problem is, I open up the video, it plays fine for about 3 or 4 minutes, then the audio keeps playing and the video starts to get out of sync, like it's lagging. It gets so bad I can't even watch it. I was thinking about downloading VLC, but my internet is down at home right now. Any suggestions, maby there are settings i can change to help? Also, I do have a virus scan running, but that shouldn't make it lag out like this, since i tried opening it up in WMP and it plays fine, just without subs. EDIT: Took a look at some of the video information, and it's not great at all. Framerate: 18-21 Sync offset: avg: ~170ms dev: ~365ms Frames ( after approx 10 mins): drawn: 6000 Dropped: 1875 Jitter: 95ms Bitrate avg: 23Kb/s I also noticed that there are 3 buffers, and the 3rd isn't doing anything at all, not sure if it is or not so basically what I'm seeing is that it's dropping approximatly 1/4 of the frames, for what reason I have no clue.
