Hi, |
| 2 |
|
| 3 |
I got strange problems (probably) with dvd+rw-tools-6.1-r1: |
| 4 |
|
| 5 |
There are three files (recordings from my DVBT-receiver): |
| 6 |
|
| 7 |
-r--r--r-- 1 root root 1205874688 Jul 2 10:14 2006-04-02_20-15_Ice_Age.mpg |
| 8 |
-r--r--r-- 1 root root 1492150272 Jun 30 20:29 2006-06-27_22-15_Twister.mpg |
| 9 |
-r--r--r-- 1 root root 1754710016 Jun 30 18:20 2006-06-28_20-15_Final_Fantasy.mpg |
| 10 |
|
| 11 |
which I burned with k3b onto a DVD+RW media. |
| 12 |
The process itsself does not produce any problems. Even the |
| 13 |
verify-function reports "Success". |
| 14 |
|
| 15 |
Then I ejected the medium, reinserted again, mounted the DVD and |
| 16 |
cat * > /dev/null all files. |
| 17 |
|
| 18 |
Result: |
| 19 |
cat: 2006-06-28_20-15_Final_Fantasy.mpg: Input/output error |
| 20 |
|
| 21 |
The kernel log files contains this: |
| 22 |
|

K3b was instructed not to produce a multisession DVD and not to use |
| 37 |
UDF-structures. |
| 38 |
|
| 39 |
Strange enough, I can repeat this with another medium and get back |
| 40 |
the same block reported in the log files. |
| 41 |
|
| 42 |
Now... |
| 43 |
|
| 44 |
Then I used dd to read the whole DVD in one go. The read process as |
| 45 |
such completes without any error. So I think medai and burner are |
| 46 |
not guilty for this. |
| 47 |
|
| 48 |
However when cat'ing the files from the image, which I mounted via |
| 49 |
loop-device, I got the same error as those described above. |
| 50 |
|
| 51 |
The I used readcd to perform the same thing, mounted the image via |
| 52 |
loop-device ans VOILA! the files could be read with correct sized |
| 53 |
files from the image without any error. |
| 54 |
|
| 55 |
I could repeat the experiment by using growisofs from the comandline |
| 56 |
with comparable results (the files were written in a different order, |
| 57 |
though). |
| 58 |
|
| 59 |
An image generated with k3b (which then does not use growisofs) is |
| 60 |
ok. |
| 61 |
|
| 62 |
Here I stand, head in hand, turn my face to the wall.... |
| 63 |
|
| 64 |
I have simply no clue, who or what is playing bad jokes at me... |
| 65 |
|
| 66 |
My system: |
| 67 |
Gentoo Linux (32bit) with vanilla kernel 2.6.17.3 (newest stable) |
| 68 |
dvd+rw-tools 6.1 |
| 69 |
mkisofs 2.0 (as reported by growisofs) |
| 70 |
k3b 0.12.6 |
| 71 |
|
| 72 |
Hardware: |
| 73 |
AMD64 X2 3800+ |
| 74 |
1GB RAM |
| 75 |
Asus AV8 motherboard |
| 76 |
LG 4163B (firmware A106, newest release) DVD/CD-Burner |
| 77 |
|
| 78 |
|
| 79 |
Any help to resolve the problem described above is very appreciated. |
| 80 |
