I don’t know if anyone has encoutered this problem with their WD media player. I have a WD TV Live model and the firmware is up to date. some movies I played fast forward or freezed. I have to press pause and play to continue watching the movies. otherwise the video would completely be frozen and I have to restart the unit. Not all my movies encounter this issue. As far as, I can tell there is nothing wrong with the file. I use VOB format. It’s a straight backup of the original DVD.
