NEC has introduced a new feature with the 3540A model: When too many
buffer underruns occur, it reduces the write speed. I can, on Windows
XP, reproduce the problem that too many buffer underruns occur on this
drive when using cdrecord-prodvd at 8x speed, so that it falls back to
6x speed right after the zone change to 8x.
As cdrecord meters the max DMA speed before accepting a write speed,
it seems to be unlikely that there are many buffer underruns.
