I have the impression that dvd+rw-tools is no longer being
maintained upstream. The latest update appears to be more
than a year old.

I'm curious what kind of integrity tests you run under
Windows. It's possible the disk is *partly* unreadable, which
is not much better than having a coaster when you're dealing
with important data.

I always burn with speed=1 when using no-name (or generic)
media DVD+R media (which causes my Lite-On DVDRW LDW-851S to
burn at its slowest speed of 2.4x).

Actually, burning higher than 2.4x produces disks that are
likely to be partly or totally unreadable in my non-burner
unit. So if I'm planning to lend or hand it out, I always
burn with speed=1 and verify (dd, readcd or dvdisaster) the
disk on my other DVD/CDRW combo unit.
