3. What kind of dvd media you use - RW or W


DVD+RW

I have read a lot of complains that RW media is not good for this
task. Can you try with normal blank DVD?


Usually DVD+RW/R is slightly more reliable for data burning than
DVD-RW/R ...

But it might be worth checking the capabilities of the drive with.

wodim -prcap -dev=/dev/dvd





This is what I got

Andredo@linux-Andre:~> wodim -prcap -dev=/dev/dvd
wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK


Try as root, if this error disappears you may have to set the suid ...


limits.Device type : Removable CD-ROM

Your DVD does not burn DVD+ media use DVD- media



My error, seems that output does distinguish DVD- and DVD+ media
capabilities (I thought it used to but memory must have been playing
tricks last night).


Yet I have this same file burned on a DVD+ , as SPD2412 should do!

- From your original output in your earlier mail....

Number of supported write speeds: 1
Write speed # 0: 706 kB/s CLV/PCAV (CD 4x, DVD 0x)

This does not look correct to me... I get on a different device....

Number of supported write speeds: 2
Write speed # 0: 5540 kB/s CLV/PCAV (CD 31x, DVD 4x)
Write speed # 1: 3324 kB/s CLV/PCAV (CD 18x, DVD 2x)

With a DVD+RW in...

and...

Number of supported write speeds: 8
Write speed # 0: 8467 kB/s CLV/PCAV (CD 48x, DVD 6x)
Write speed # 1: 7056 kB/s CLV/PCAV (CD 40x, DVD 5x)
Write speed # 2: 5644 kB/s CLV/PCAV (CD 32x, DVD 4x)

Write speed # 6: 1764 kB/s CLV/PCAV (CD 10x, DVD 1x)
Write speed # 7: 705 kB/s CLV/PCAV (CD 4x, DVD 0x)

with no media in ...

Plus some further info in both cases... This looks rather odd but it
seems as if the available modes are adjusted according to what media is
in the device. I would do a few experiments to see what is being reported.

At last I cleared a disk with

growisofs -dvd-compat -Z /dev/dvd=/dev/zero

and burned again with

growisofs -dvd-compat -Z /dev/dvd=openSUSE-11.0-DVD-i386.iso

and got the same as with K3b and Nerolinux:

32 items 26 files (15.9 MB total) 6 maps

and no possibility to even see that in Vista.

So I have learned much, I'm very thankfull to those who did suggestions and bought the openSUSE box!!!
