DVDisaster v0.79.3 experimental

Alpha (developer) versions

Help us testing! This page contains experimental dvdisaster versions which are created on the way to the next stable release.
A word of caution: This version is still evolving and some parts are not yet implemented. It may contain severe bugs and fail in non-obvious ways, even in functions which worked in previous versions. Do not process important data with this version and do not keep images and error correction data for archival purposes; that's what the stable version 0.72 is for.

All platforms: These releases contain major internal changes compared to 0.72.x. Please use them carefully.

CHANGES

0.79.3 (21-Nov-2010)

• GNU/Linux: Starting with this version the SG_IO driver is used by default for accessing optical drives; the previously used CDROM_SEND_PACKET driver can be selected optionally. Driver defaults were the other way around in previous versions; but in recent Linux kernels the SG_IO driver provides better compatibility.
• Michael Klein provided Altivec optimization for the RS03 codec.

0.79.2 (28-Feb-2010)

• A binary package for Mac OS X is available now. The Mac OS X development environment has been updated; this removed some glitches in the graphical user interface.
• Development of the RS03 codec makes progress, but is far from being finished yet.

0.79.1 (07-Feb-2010)

• The SCSI layer contains a workaround for buggy chipsets found in recent drives. Starting a read or scan operation would case a system freeze with such drives. The problem seems to be especially visible under Windows XP, but other OS might expose similar failures. Please test if these drives are working now, and also report if some drives stopped working which were okay previously.
• A reference implementation of the RS03 codec is included. This version is only supplied so that interested people can compare it against its specification. Take care and do not use it for productive work. The final version will be released with version 0.80.

Windows: All components of the development environment and the supplied libraries have been updated. Please test whether the graphical user interface and localization still work as expected.
