I must be doing something wrong. I'm converting 720p mkv's to m4v format with Handbrake. I've got the latest version and I'm using Apple TV - Legacy Preset. I have this one mkv that every time I convert it drops out of sync. Others seem ok but this one is wonky. Any ideas or advice? Is VisualHub better for handling this conversion? Am I using the right settings? I read on a few sites that the ATV Legacy Preset was better than the new ATV Preset....Do I have to make any other changes before beginning the conversion. Thanks in advance.
