Audio out of sync with video


When I stream a movie using my mac mini directly to my TV the audio and video are in sync. When I play the audio through my stereo(mac to DAC to amp)the video and audio are out of sync. Any ideas as to how to fix this.
thanks.

Your media player should have the ability to sync audio and video timing. If not, try VLC.
Thanks, but I am streaming from Netflix. I guess I should have mentioned that.
