With Factory (RC2?), I have lot of problems to write dvd's

* k3b still don't write BD (sould be on 2.0, we have 1.92?)

I openned bugs, but I see that k3b 2.0 is out

You need the real cdrecord to write BluRay media. A problem is that Suse still by default does not distribute the official software.

I know about the problem between cdrecord and wodim and wont say anything on it, because I'm not the right person to do so :-(. I acknowledge your work !

wodim is based on a cdrecord from September 2004 with additional bugs added by Debian and with the DVD support code ripped off and replaced by something that works on weekends wit full-moon. As BluRay support was added in 2007, it is missing in wodim. As support for files > 4 GB was added to mkisofs in Summer 2006, this is obviously something that is missing also in "genisoimage". Regardless on whether you use growisofs or cdrecord for writing, you need a recent version of mkisofs and this is only available with the original cdrtools package. Otherwise you will get into problems with large files. Also note that cdrtools has no legal problems but wodim (cdrkit) is in conflict with GPL and Copyright law and thus cannot legally distributed. I encourage all Linux distributors to align their strategies with legal facts and usability.

however I *can* burn BD with growisofr, but not from k3b (and at a very reduced speed, but this may not be related), so it takes 3 hours on linux (and only 3/4 hour on windows :-()

The reduced speed seems to be a result of the way growisofs works. Writing formatted BD-R media is slow and growisofs tries to handle everything similar to DVD+R/RW. This results on formatting BD-R before writing. Cdrecord writes to unformatted BD-R. Unfortunately, I cannot say much for cdrecord regarding speed as there was close to no feedback yet. I did do most of my tests using a USB2 connected writer with BD-RE media and I get write speeds that are close to the expected values. Note that if you have a BD writer and if you see better speed on MS-WIN, I am very interested to see SCSI command traces (from a program that is able to snoop SCSI commands) and there would be definitely a reaction in the cdrtools code. As a hint: there have been 50 cdrtools releases since cdrtools introduced BD support, there have been 2 growisofs releases since growisofs introduced BD support. The last cdrtools release is one month old and this was 3.00-final. The last growisofs release is from March 2008 and there are several known bugs in growisofs, see e.g.: https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/600770 https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/600869 https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/600871 https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/600893 https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/600896 https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/600898 https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/601092 https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/601125 These are mostly systematic problems (e.g. from reusing buffers that are incompletely initialized). The author of growisofs was very silent during the past 2.5 years. I cannot speak for his intention on lomg term support. Long term support on the other side is a well known fact for softare from me (see e.g. star that is available since 1982 and still actively maintained). All my software is and always was developed in close contact to it's users and in former times, there have been several times where feedback from SCSI snoops has been integrated.

I have such a BD writer (LG, USB, may be the same as yours) and an XP computer. On XP I use the software given with the writer, but have no idea of how to log the scsi commands?

There is a software called BusHound that we used before. It partially works for free. We have been able to use the free variant in order to reverse engineer all secret Plextor commands and a friend who works for SCO did get the permission from SCO 4 years ago to buy a version for analysing how commercial software handles multi-border writing with DVDs.

I don't challenge this. All this story is damageable. I could install your cdrecord from obs and I write with it now

There is a binary cdrtools-3.00 package for Suse, you could install this.

Since 11.3 openSUSE also provides cdrskin (package libburnia-tools), from http://libburnia-project.org/. With newer versions available at X11:xfce. I don't use my writer... ever? If you use it more, it's a program that could use some testing. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
