I'm trying to get videos working well through Coreplayer, but I keep getting this screen tearing/smearing/glitching effect, especially in fast paced scenes; only ones that work well are the ones I stream through SMTube. Because of this I have to switch to XBMC for movies/TV shows which doesn't have this issue but can stutter badly, especially on high-definition content. Anything I can do to fix this? Thanks.
