[Thomas Valentin <Thomas.Valentin@astrum.de>]

my dvd drive is dma enabled (hdparm -d1 /dev/hdd)

some dvds work perfectly some work in the beginning and after 1 minute the
playback is bucking ...

i thought that those dvds that work are not encrypted (vdr is about < 20 %)
and the others are encrypted
and decss library eats up all the cpu (vdr is 99%)....

i really dont know why some work  ...

Even your old box should be able to play DVD's without much problems. I have

even had reports from people with slower system being able to play dvd's.
DeCSS during playback does not take much, only the key cracking needed
before 
the playback can start requires some time and even that can be avoided by 
using proper player keys. Read the ML archive on how to do this and get the 
dvdinstall.tar.gz archive.
The AC3 decoding needed for most dvd's is a bit more resource hungry, but 
still a PII 350 should have no problems. It can be improved by building 
liba52 with the djbfft library, again check the ML on how to do this.
Also, most dvd speed problems come from dma not being enabled for the drive,

even my 1.1GHz AMD chockes without the dma setting (hint: man hdparm).

Hope that helps
