Audio out of sync with MP4 and Sony Bravia
Folks,
I have a serious problem with Serviio and my Sony Bravia KDL-40NX705 (Europe).
Setting up Serviio was an absolute breeze: just start, configure the folders, and pronto! everything worked right out of the box -- both MPEG2 (my vanilla .vob files from unmodified DVD rips) and M4V (encoded from such a rip with Handbrake to H.264/AAC+AC3) played nicely and without problems. I then started to encode some random other DVDs (again M4V), and ended up with movies in which the audio stream lags behind the video stream for about four or five (!) seconds.
It does not seem to be an "infrastructure" issue -- as said, the older M4V files play nicely. I have the latest iMac model with a 3.6GHz Core i5 CPU, and a fast 802.11n WiFi network, so this shouldn't be an issue (no HD material). Also, when playing back the files on my Mac (using Perian), the lag is just not there.
So the only things to blame are a) Handbrake, b) my Sony Bravia, or c) Serviio.
MediaInfo Mac reports the following on the two files (where the first one works, and the second one lags):
and
I noticed that for the former rip, I used an older Handbrake version. Also, a few settings are slightly different, but I don't really have an idea what Handbrake is doing, so I might overlook something in the encoder settings -- any help would be really appreciated!
Thanks,
lxndr

I noticed that for the former rip, I used an older Handbrake version. Also, a few settings are slightly different, but I don't really have an idea what Handbrake is doing, so I might overlook something in the encoder settings -- any help would be really appreciated!
