dvd+rw-tools on liteon drive

Hi Andy

I have a liteon 812S dual format 8x dvd burner. I have found that when
burning ritek 4x dvd-r, the discs get burnt at 8x resulting in errors.
Also, the discs get burnt at 8x even when i specify to burn them at 2x,
4x or 8x. I use k3b, however I have also tested it on the command line.

dvd+rw-format reports the following:

root : dvd+rw-format /dev/cdroms/cdrom1
* DVD¿?RW/-RAM format utility by <appro@fy.chalmers.se>, version 4.10.
:-( mounted media doesn't appear to be DVD¿?RW or DVD-RAM

This is as of version 5.20.4.10.8, however version 5.13.4.7.4 would
report that the disc was an 8x disc.

following is a list of what the disc would get burnt at given different
speed parameters:
specified    actual
1x             4x
2x             8x
4x             8x
8x             8x

This is my second batch of ritek dvd-r. The first batch all burnt at 4x
without any hassles. I think that was because the last batch of dvd-r
were detected as 4x, not 8x.

If you have any ideas, they would be greatly appreciated. If you want
any other information, just let us know :-)

Cheers,

Brad
