    Hi, I I've got a bunch of 1080p videos in MKV. When I play them using VLC and switch the video to a different scene (say 20 minutes ahead), artifacts appear throughout the video for a few seconds and then it disappears. I have this on about half of my MKV 1080p Videos. Is this normal? This only occurs when I manually switch to a different scene. If I play the video straight through then it plays fine. This occurs on both my Mac Pro and Windows Vista Computer. Are my videos corrupt? I don't notice this on my Mac Pro when using Movist when switching scenes. Any help is greatly appreciated

    Know that isn't normal, though I wouldn't worry too much.

    I really don't know anything about MKV, but it sounds like when you skip ahead it is using the previous key frame and you will see errors until a new key frame comes up in the stream. The frames following a key frame are differentials from that key, so it is to be expected. This is an artifact of higher compression streams.
