If you are using ffmpeg to create DVD-compliant mpeg-2 files, there is something important to keep in mind. This is the -maxrate option.

I have found that without this option, there is the occasional bitrate spike that will exceed the 9Mbps limit for DVD’s. On some DVD players, this will present itself as a skip in the audio followed by audio and video coming out of synchronization.

When encoding for DVD, be sure to use -maxrate 7500k to keep all video spikes within spec. You might be able raise the max above 7500k and still be within spec, but this is the setting I use.
