I am using a Roku for playback and a ReadyNAS as a server. Up until a few months ago everything worked fine. Now almost every time I start a movie or TV show, the video starts perhaps 10 seconds into the file and the audio starts at zero. So the audio lags the video. I pause, then hit rewind once, then play and everything syncs up and stays that way for the whole show/movie.
Any idea how to fix this?
