A couple of weeks ago, I wrote to the list saying that I was having
problems with DVD playback. The playback was stuttering and very jerky.
DMA was already enabled for the drive so that wasn't it.

Well, last night I made a change to a setting that has solved the
problem. DVD playback is now as smooth as silk.

The setting I changed was as follows:

In YAST2->SYSTEM->Powertweak Configuration, under the configuration
options, I expanded the "Hardware" option. Then, I expanded the "Disk"
choice followed by the "HDD" (my DVD drive device) choice.

Two more choices then present themselves. The first,
"hdd_ELEVATOR_READ_LATENCY" is the one that I adjusted. The default
value was 128. I lowered it to 64. That did it.

I just wanted to post this in case there's someone else out there having
the same problem I had. First & foremost, make sure you have DMA set for
your DVD drive. If it is, and you still have jerky playback, try the
above.
