When I used Handbrake, I always had audio sync issues. I could never figure out what I was doing wrong. That was on Windows. Now that I'm on a Mac, perhaps it'll go better, though I don't have the need to use it much anymore.

I've never had any audio sync problems with Handbrake, then again I've never done anything 'exotic' (basically encode my dvd's to x264+audio passthrough) and everything has worked fine.

  Back when you wanted to encode a DVD to the size of one (or maybe two) CDs, having audio-passthrough was not an option. You typically re-encoded the data from 384-448kbps (for AC3-surround) down to 128kbps stereo. For that you used MP3 audio. I also recall the earlier Frauenhofer MP3 codecs incorrectly reported audible length of chunk-sizes (or something like that) causing incremental audio-skew and sync-issues with the corresponding video the longer into the movie you came. It seemed impossible to fix and was terribly frustrating. Eventually the tools caught up and patched up the data, or we got better tools (like lame) which didn't produce the faulty artefacts to begin with. Maybe this is what he's talking about, as the Frauenhofer MP3-codec was very much a Windows-only thing.

During the last three years I have installed Handbrake twice to convert a just created WMV to H.264/AAC. On both occasions Handbrake just failed to do anything for the file and I ended up uninstalling it. Later I created a kilometer long ffmpeg command line and been happily creating files to be used with Flowplayer. Those files have been playing without any issues on iOS, Android, Windows, Linux and MacOSX. I wonder why this Windows Live Movie Maker output turned out to be problematic for Handbrake, but on the other hand now I haven't needed to start any video conversion GUI for a long time.
