Hi folks,
If I try to write an 8x DVD-R (Verbatim), then the writer
(LG GSA-4082B, firmware A208) starts with 4x as expected,
but later it drops to some arbitrary value (about 2x).
After a while it goes up to 4x again, but it never reaches
the promissed 8x.
Below you can find a sample session.
Writing the old Verbatim DVD-R 4x medias was never a problem.
If I use "growisofs -speed=4" then there is no problem with
the 8x medias, either (except for the lost performance).
Regards
Harri
