hdc is a dvd recorder Lite-On DVDRW SHM-165P6S
hdd is a cd burner LG CD-RW CED-8083B

I can on both play, read and write cds very well.
On hdc I can write dvd-r and dvd+rws very well. But on reading
I get similar error commands for dvd roms and self written dvds.
I tested also with another dvd-rom drive and got the same errors. The dvdrs are read well after some tries but the reading of dvd-roms is bad some have no sound and i get with mplayer the message "can't seek to block" followed by a big number. 
I can circumvent this by disabling dma transfer and playing a later chapter and seek back to the previous one.
But i cannot use Dvd-Ram if i insert them they are mounted as root not as the user if they are mounted. But the mount command shows that the gid and uid set to the user, the dir under /media for the drive ihas root permissions. If I mount
from the drive I get a lot of io errors like this

I have dapper installed on an amd64 sempron 2800+. Before dapper I used
a self made system with kernel 2.6.13 with a amd k6-3. There I had the
same cd burner and the cd-rom i tested also with the new system. I
hadn't this errors before. Disabling dma and using the generic ide
driver doesn't help.

Thank you for help.
