Re: [AV Media Matters] SVHS Correction & Preservation

DVDs/DVD-Rs are great for access and distribution but not for archiving
most
legacy archival material.
One archival issue with DVDs/DVD-Rs is that heavy compression is used
and
compression has two potential problems. One is the loss of the detailed
information like fluffy clouds, fine hair, grass, etc and archival
material
should never be degraded. The other potential problem with compression
is
whether or not compression artifacts will show up in the future when the
DVD
is copied to a newer format.
The second archival issue is how stable the medium is. At this time, I
trust
only Mitsui Gold.
The third archival issue is interchange. Will your DVD-Rs play on all
makes
of DVD players? Our evidence with CD-Rs is that the answer is no and
the
density of DVDs is much greater than CDs.
