DVD playing problems

Hi friends,
I am having the following problems while playing the DVDs,

I am using suse 10 on my laptop with ATI 340M GPU, with 3d acceleration
enabled by using ATI Drivers,

Now the problem is , the dvd movie is not clear and crisp as it is played in
my windows machine, it is blurry at edges and when there is motion in
picture ther is a sort of blurr,
recently i was playing mp3 songs in my xmms and started A dvd movie.. after
playing the intro ads etc, it came to the menu screen,
 and poped a error message saying that the sound device is busy, its being
used by another application,
then i close xmms and tried playing, it gave the same message,
I rebooted the machine, and the same error message is being given from then.
Can anyone suggest me what to do to rectify this?
and also to get clear picture?
regards

Air Conditioners and Computers are similar in some ways. Both are
useless when you open 'Windows'.
