Thank you for your input.
I already tried all available -vsync options. They do not change anything if 
applied to the video input (probably as the raw video data does not contain 
any timestamps so they have to generated by ffmpeg), and only the 
option -vsync drop affects the result if applied to the audio stream, but 
does not solve my problem. Still, all audio packets are written to the very 
first part of the resulting file. But all timestamps of the encoded packages 
(video and audio) are correct, so it causes no problem for playback on most 
software players. It certainly won't work fine for an optical medium.
