I use to be able to play any dvd/blu ray i had ripped to h264 using dvdfab(legit copy) in vlc. all of a sudden. it only plays audio. dvds play fine in the original format. I even tried using Nero reencode to convert a short movie as a test. same results. they play fine in windows movie and tv app(except no sound because of the dts track(unless I convert to ac3, then it plays audio). I have uninstalled vlc and reinstalled it many times, but cant get h264 to display anymore. this has been going on now for over a week. I haven't changed any settings on my computer in the last few months. i do keep dvdfab updated when ever a update is released.
