/* This solves a problem with Pioneer DVR-216D.
Writing of sequential DVD-R[W] happens unnaturally fast and leaves no
impact on the media. The drive stalls at the end of the burn run. Only a
power cycle makes it usable again.
Apparent reason:
One may not read the buffer capacity more than once before it is full
and physical burning begun. Strangely this happens only with libburn and
cdrecord-2.01.01a64 -v which both write DVD-R in 32 KB chunks. With
wodim's 62 KB chunks there is no endless drive business.
