Description George Dunlap 2007-03-24 15:29:45 UTC
Description of problem:
When I try to burn a DVD+R on my laptop, cdrecord correctly identifies the
medium as DVD+R.  However, it then complains that it can't find cdrecord-ProDVD
in the path and that I need a license.  It proceeds to use the CD driver
instead(!) and although it complains that the .iso is too large, continues
anyway, producing a useless DVD.

cdrecord-ProDVD hasn't existed for some time now, as the DVD burning capability
ahs been folded into the OSS version of cdrecord.

I downloaded the latest version of cdrecord from the site, compiled, installed,
and it burns just fine.

Version-Release number of selected component (if applicable):

cdrecord 2.01-10

How reproducible:


Steps to Reproduce:
1. Insert blank DVD+R
2. cdrecord -v -dao filename.iso
Actual results:
* Looks and fails to find cdrecord-ProDVD
* Falls back to cd driver
* Detects size mismatch but doesn't stop
* Resulting in a trashed DVD+R

Expected results:
It should do one of the following:
1) Correctly burn the DVD (using latest changes from OSS cdrecord)
2) Fail rather than falling back to the CD driver
 or at very least
3) Fail when it detects the size mismatch.

Additional info:
The man page must be way out of sync.  It mentions the mmc_dvdplus driver (along
with a host of other ones), but when you try to specify that driver, cdrecord
says it doesn't exist.

  I have successfully used a Sony DW-G120A drive to write to both a Phillips
DVD+RW and a Maxell DVD+R, even though ugly-looking error messages appear during
burning.  In fact, growisofs is incapable of providing the padding necessary to
avoid the kernel read-ahead bug, so using cdrecord is the only way to do it.

Comment 4 Jason McCormick 2007-04-03 18:21:36 UTC
I'm seeing this exact problem except that I don't end up with a coaster.  I get
the error about ProDVD and falling back to CDs and then the program aborts.  I
have a Philips DVD+/-RW DVD8801.  Other tools like growisofs work just fine.

Comment 5 Andre Robatino 2007-04-28 06:48:35 UTC
  I successfully made a DVD backup on 3/29, but upon trying it on 4/27, cdrecord
aborted.  I thought it was the new 2944 kernel, but after booting into the same
2933 kernel I was using on 3/29, it still aborted.  So some other update within
the past month must be responsible.

Comment 7 Andre Robatino 2007-05-07 18:01:46 UTC
  I'm concerned about this bug because in order to avoid the readahead bug when
burning a Fedora DVD (and hence avoid the mediacheck failure) it's necessary to
have padding on the disc after the ISO itself.  Cdrecord but not growisofs is
capable of this.  Are there any other burning tools that can do the same?  I
once tried using dd to manually add zero padding after the ISO.  The resulting
disc passed mediacheck but for some reason couldn't be booted properly.  So I
prefer not to go that route.

Comment 8 Andre Robatino 2007-06-05 20:22:08 UTC
  The F7 fork of cdrecord (wodim) burns DVDs for me without any errors at all.
