argh I mixed up libdvdcss and libdvdread :) (libdvdcss should be 0.0.3 nothing 
else).

btw. I just changed my system from SuSE to RedHat and now have a very strange 
problem :(

[root at astral atmosfear]# /sbin/hdparm -c1 -d1 -X34 -u1 -k1 /dev/hdb

/dev/hdb:
 setting 32-bit I/O support flag to 1
 setting unmaskirq to 1 (on)
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 setting keep_settings to 1 (on)
 setting xfermode to 34 (multiword DMA mode2)
 I/O support  =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  0 (off)
 keepsettings =  1 (on)

I don't have the slightest idea why it fails to enable DMA, it used to work 
fine on SuSE (maybe because of different hdparm or kernel ver.)
