Have you tried another show/movie?
I tried a TV series and it was out of sync (which also has a history of being out of sync sometimes on my htpc) but I just tried The Bourne Identity and the audio was synced correct.
v 1.3.0 build 246Yes...I tried a few different shows, and I tried uninstalling and reinstalling, and tried rebooting....
Which netflix app are you using?
