DVD+RW software for (Open)BSD
By Maarten Hofman
Currently there are many different formats in which DVD are written: DVD-R, DVD-RW, DVD+R, DVD+RW and DVD-RAM. DVD-R and DVD-RW are supported by the cdrecord tools, which are available as a package. DVD-RAM is not really a DVD format, but a new system. DVD+R and DVD+RW are new formats, promoted by Philips (and several other companies) with different advantages and disadvantages than the other formats.
For Linux, there are currently two different angles towards DVD+RW support: a kernel implementation, which will allow you to access the DVD directly, format it with a file system of your choice and use it as if it were a hard disk (though will a limited number of writes for each sector); and a set of tools, developed by Andy Polyakov, which allow formating DVD+RW disks and writing a dvd-video or ISO9660 file system on a DVD+RW or DVD+R disk. These tools are described at http://fy.chalmers.se/~appro/linux/DVD+RW/ and include the source codes.
These source codes use Linux-specific CD-ROM access and do therefore not compile under (Open)BSD. I rewrote the CD-ROM access to SCSI-3 commands and tested the result with my Philips DVD+RW drive. To my own surprise, they worked. I decided to make a WWW-page that contains the discussion about them and the rewritten source codes and made them available at http://www.mosha.net/~jen/OpenBSD/DVDRW/ so that other people can use them.
Of course, currently there will not be many people that use a DVD+RW with OpenBSD, but hopefully this might change now. I do not know whether they compile on any other BSD system, because I do not have access to those.
If the image to be written on the DVD+RW is generated by mkisofs 1.14 (or higher) using the -dvd-video video option, it contains the required structure of video and audio directories, and you change the booktype of the DVD to DVD-ROM afterwards using the dvdbooktype command (included in the tool set), then it will actually play in a number of DVD players.

what I mean by that is I can put a blank dvd rw disc into my plextor burner and copy any number of types of files to keep for old lang zine.
I would expect to retrieve this dvd some years later and be able to look at what I had saved.
The reason I picked dvd over cd is my obvious thought that I could store more info on them.
I am having the most frustrating time in doing this. I have had about every kind of error message known to this universe. compatablity, read only, wrong format etc etc etc.
Isn't there a simple way for an old person to do what I'm wanting to do.
I am using an Intel board, intel chipset, intel processor(3.2 gig) and 2 gig of ram.
Please have someone put me out of my mizzory.
