Hi,
I got strange problems (probably) with dvd+rw-tools-6.1-r1:
There are three files (recordings from my DVBT-receiver):
-r--r--r-- 1 root root 1205874688 Jul 2 10:14 2006-04-02_20-15_Ice_Age.mpg
-r--r--r-- 1 root root 1492150272 Jun 30 20:29 2006-06-27_22-15_Twister.mpg
-r--r--r-- 1 root root 1754710016 Jun 30 18:20
2006-06-28_20-15_Final_Fantasy.mpg
which I burned with k3b onto a DVD+RW media.
The process itsself does not produce any problems. Even the
verify-function reports "Success".
Then I ejected the medium, reinserted again, mounted the DVD and
cat * > /dev/null all files.
Result:
cat: 2006-06-28_20-15_Final_Fantasy.mpg: Input/output error
The kernel log files contains this:

K3b was instructed not to produce a multisession DVD and not to use
UDF-structures.
Strange enough, I can repeat this with another medium and get back
the same block reported in the log files.
Now...
Then I used dd to read the whole DVD in one go. The read process as
such completes without any error. So I think medai and burner are
not guilty for this.
However when cat'ing the files from the image, which I mounted via
loop-device, I got the same error as those described above.
The I used readcd to perform the same thing, mounted the image via
loop-device ans VOILA! the files could be read with correct sized
files from the image without any error.
I could repeat the experiment by using growisofs from the comandline
with comparable results (the files were written in a different order,
though).
An image generated with k3b (which then does not use growisofs) is
ok.
Here I stand, head in hand, turn my face to the wall....
I have simply no clue, who or what is playing bad jokes at me...
My system:
Gentoo Linux (32bit) with vanilla kernel 2.6.17.3 (newest stable)
dvd+rw-tools 6.1
mkisofs 2.0 (as reported by growisofs)
k3b 0.12.6
Hardware:
AMD64 X2 3800+
1GB RAM
Asus AV8 motherboard
LG 4163B (firmware A106, newest release) DVD/CD-Burner
Any help to resolve the problem described above is very appreciated.
Thank you !
Kind regards,
mcc
