Any such software when used with an EasyWrite (Mount Rainier) compliant drive will produce much more reliable results. Years ago I tried Adaptec's and Ahead's solutions with CD-R/W and without hardware support and standardization it was awful. With EasyWrite CD-RW (MRW) and InCD, the problems virtually disappeared. But I have since moved on to the uber reliable DVD-RAM which I tested with both InCD and Matsushita's driver and found the latter to be better since only it works with TrueCrypt.
InCD has the advantage in supporting the latest UDF standard of 2.60 vs Matsushita's 2.00. Limiting usage to 2.0x ensures that Windows XP/2003 can read the discs without additional drivers, but I would prefer the option of at least Metadata Partition from 2.50.
I have not used Veritas/Sonic DLA but understand it also supports DVD-RAM. There are versions available for free from the various system builders and at least one is from June 2005 but in any case my impression is that it has not been kept up to date (apparently only supporting UDF 1.50?).
The really troubling thing about DLA is this:
Are there any software compatibility issues with DLA and 3rd Party applications?
If 3rd Party applications use the device in which DLA uses to write to the media, drive contention issues will exist and could result in a device being inaccessible by DLA. These applications include other drive letter software applications and mastering applications.
Sonic is aware of drive contention issues with the following applications but is not limited to this list:
Nero Burning ROM
Roxio Easy CD Creator
NTI CD Maker Pro
These applications should be disabled prior to using DLA or vice versa.
I have not had any issue with either InCD or Matsushita while Nero Burning ROM or PowerDVD are installed. I understand DLA can be toggled off, but if it was required when using NBR or other software it could be a real hassle.
Since Sonic Solutions aquired Veritas and then Roxio (previously spun-off from Adaptec), I would expect the offerings to narrow (focussing either on DLA or Drag-to-Disc). Hopefully for DVD-RAM users, Matsushita will update the UDF specs in its driver especially with 2.50 and 2.60 being the standards for the forthcoming HD/BD formats.
Since there is no longer much of a premium for DVD-RAM and the available hardware options are increasing, and 16x is forthcoming, I would suggest not bothering with the other formats, but again, at least make sure to use EasyWrite drives rather than relying soley upon software.
