Jorg has even commented as such.  If the drive lets him use the same, -R
command set to record +R, then it "functionally" works.  But it doesn't
mean it records +R as it should be.

Pioneer's DVD-RW was the original and only drive Jorg supported in
CDRecord 1.x (before ProDVD), which DVDRecord is largely based on.

Well, I wouldn't blame Jorg.  He's just supporting what "functionally"
works on various drives.  It's really the fact that DVD+RW (and +R)
don't work like -R (or -RW in record emulation) -- both drive and media.

Again, Pioneer's DVD-RW was the original and only drive Jorg supported
in CDRecord 1.x (before ProDVD), which DVDRecord is largely based on.

I would recommend you _avoid_ -RW and +RW for anything critical.  The
CDRecord set of programs were designed for how CD-R and DVD-R work, and
you don't want to "record" to CD-RW, DVD-RW or DVD+RW in "emulation"
mode.  DVD+R works much like that from CDRecord as well.

Yes, and use the CDRecord programs with CD-R and DVD-R only.

Avoid using DVD-RW in "record" emulation mode.

I guess you _could_ use DVD-RAM in "record" emulation mode, but you
don't need to since DVD-RAM is pre-formatted and directly usable.

> 2) if u wanna use +R media, use growisofs, 

Excactly!  You want to use use the kernel's block read/write access for
DVD+RW (and DVD+R), which is what the drives (and media) were designed
for.

I believe all the new interactive GUI programs now use the kernel's
block read/write access to do such anyway.  I almost always record to -R
(and rewrite to -RAM) so I'm not the expert on those programs.

Thanx for the backup.

I know I came off as a jerk, but I'm really just trying to help new
people -- this person had a LG GSA series drive.  And I really didn't
want to get back into what had already been covered before, from someone
else's experience with Pioneer -RW drives, dislike of CDRecord, etc...
