<b><a name="pronounce">1.1 How is "dvdisaster" pronounced?</a></b><p>
|
|
Since the word stems from the english language, simply spell "dv" before
|
|
saying "disaster". Perhaps "dee-vee-disaster" is a suitable
|
|
phonetic circumscription.
|
|

|
|
|
|
<b><a name="pipo">1.2 What are quality scans and why don't you support more?</a></b><p>
|
|
Optical media have a built-in error correction which is similar to
|
|
the method used in dvdisaster.
|
|
Some drives can report the number of errors corrected
|
|
while reading a medium. This provides a rough estimate
|
|
of the writing and media qualities.<p>
|
|
|
|
Since dvdisaster is free software, it can only include code and information
|
|
which can be redistributed freely. This is currently true
|
|
for C2 <a href="howtos10.html">scanning</a> of CD media,
|
|
which is officially standardized and has free documentation available.<p>
|
|
|
|
On the other hand, DVD quality scans ("PI/PO scans") are not standardized.
|
|
Those drive vendors who support it are using proprietary programming
|
|
interfaces. The respective specifications seem not to be available
|
|
for use in free software. So we must patiently wait until manufacturers
|
|
understand that having free software available for a drive
|
|
will sell more drives. <p>

|
|
<b><a name="compat">1.3 Is dvdisaster compatible with future releases?</a></b><p>
|
|
Yes, dvdisaster files are intended for an archival time of many years.
|
|
When upgrading to a newer version of dvdisaster you can continue using
|
|
images and error correction data created from previous versions.
|
|
There is <i>no</i> need to recreate them again.
