So while trying to watch my last 3 DVDs from Netflix I've come across a tiny (but hugely annoying) problem. I'm trying to watch the DVDs on my iMac but every 2 seconds or so, the image pauses for a split second and catches itself back up. This is especially annoying and noticable during panning cuts, but its noticable throughout and I cant seem to figure out whats causing it. Plus, the sound never gets interupted, just the image. I've quit all other apps while playing the video thinking it might help but it doesn't. I don't know what else to do. Help!
