Hi, I've got my computer hooked to my HDTV with a hdmi cable. Whenever I watch something i get these random speedups which fast-forwards the movie about 3-4 seconds. They only happen once or twice each movie and usually near eachother. It dosen't matter if i watch a hd movie in a mkv container or a normal dvd, it always happens. So I wonder if anyone has the same problem or know of a soulution to it? Thanks for any help.
