A quick clarification, all my testing was done under gentoo, not using original sources from wodim/cdrecord/mkisofs/genisofs/brasero so it's possible that the issue is down to gentoo packaging rather than original sources. I haven't checked this and doubt that I will as I have stuff to be doing! -- Blast off and strike the evil Bydo empire!

Genisoimage is based on a very outdated mkisofs, it has massice bugs with graft points. It is not very likely that it might be possible to work around these bugs. As you don't describe your problems it is impossible to help. -- EMail:joerg(a)schily.isdn.cs.tu-berlin.de (home) J�rg Schilling D-13353 Berlin js(a)cs.tu-berlin.de (uni) schilling(a)fokus.fraunhofer.de (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.berlios.de/old/private/ ftp://ftp.berlios.de/pub/schily

I've already said that despite you claiming that "these bugs" that you claim can't be worked around, genisofs works fine and is doing the job. I've written multiple DVDs with it and even an 8.5 gig one. Just in case it's not quite sunk in yet; brasero and wodim and genisofs can write perfectly good DVDs including directory heirarchies. Brasero, cdrecord and mkisofs do not work, the directory heirarchy is wrecked, even though the heirarchy is very very simple; one directory with files in it. Brasero, cdrecord and mkisofs put half the files in the CD root and half in the directory. Whether this is a problem with brasero, cdrecord, mkisofs or gentoo I do not know. Claiming that wodim/genisofs will not work is very silly as I've already said that they are working fine in a situation where cdrecord/mkisofs failed. -- Blast off and strike the evil Bydo empire!

If you have a problem, you should be able to give the mkisofs commandline, a stripped down source directory tree, the expected and the observed result. If you can't, is there a problem? -- EMail:joerg(a)schily.isdn.cs.tu-berlin.de (home) J�rg Schilling D-13353 Berlin js(a)cs.tu-berlin.de (uni) schilling(a)fokus.fraunhofer.de (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.berlios.de/old/private/ ftp://ftp.berlios.de/pub/schily

The path names are a concern of mkisofs. That is what assembles the stuff you tell it to burn and makes a single iso file. That is what contains path names, etc. Now it sounds like you did not tell it to use the appropriate rock-ridge/joliet extention to make the iso. >I also burned a dual-layer 8 gig DVD+R with it last night, worked a >treat including verifying so brasero appears to fill my needs fine, >but rather puzzlingly only works properly with wodim and not cdrecord. If you could list the symptoms again, it would be useful to debugging. nd "treats path names differently " is not a symptom. |
