Use audiorate with a specified tolerance (10 or 20ms should do) before the
audio encoder.

The issues isn't specific to dvdemux:
* Audio sinks will automatically adjust for such jitter (drift-tolerance with a
default of 40ms), which is why you don't hear it when playing that pipeline
back with a audiosink.
* Most audio encoders expect perfect audio streams.

You'll have the same problem if you were to replace that live DV pipeline with
a non-live ASF pipeline (the granularity of packets in an asf file is much
lower than that of raw audio) or if you were to encode a RTP stream.
