DVD+RW and OpenBSD

Dear all,

I'm not sure if anyone is interested, but I ported/rewrote the DVD+RW tools 
from Andy Polyakov (http://fy.chalmers.se/~appro/linux/DVD+RW/) to OpenBSD 
and tested them with my Philips DVD+RW player until they worked at least 
with that drive. The result is at 
http://mosha.linux-site.net/~jen/OpenBSD/DVDRW/ .

Comments:
* This is for DVD+RW, not for DVD-RW. It can also handle DVD+R. cdrecord 
doesn't support DVD+RW, but you need it anyway to create the ISO9660 
filesystem to write on the DVD+RW (or the DVD video file system).
* The booktype code is kept compatible with windows and linux.
* Currently it only supports drives with a LUN of 0, but I added 
instructions on how to change this (untested, obviously).
* The original growisofs.c has a normal pwrite() implementation and a poor 
man implementation (using SCSI commands). For some reason, the first time I 
used it, it used the pwrite() implementation, indicating that there is some 
kernel support for DVD+RW... However, it still needed the CLOSE 
TRACK/SESSION. Also, when I tried it after that one time, it never worked 
again.

Please let me know what you think.

Greetings,
Maarten Hofman.
