I've got some really terrible dual layer dvd media someone gave me because
they couldn't get it to work on about 3 different computers with both windows
and linux. I can't get it to work either, and the messages I get are very
similar to the above, so this may be a media problem (I haven't tried any
other media because I never really had much need for it anyway, but dimly
reall the person who gave me the rotten media says he got other media to
I wish that was the problem, but I doubt it, because I paid premium price to
buy top brand media.
Is the media recommended by the drive vendor? E.g. for an LG drive the only
recommended dual-layer media is Verbatim.
well well, look what i found... interesting... today i'm having the SAME problem:
Media: Verbatim DVD-R DL, TDK DVD+R DL
Multiple brands (Verbatim/TDK) and types (+R/-R), all the same problem, which
appears when the drive tries to burn the layer switch (dvd_dual_layer_split).
No solution so far.
oh, and here is another guy with the same problem (liteon drive):
this bug doesn't look like drive or media related, i'd say there is a problem
yup, here is another guy with the same problem:
solution: use growisofs instead, chances are wodim won't be fixed.
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
