    Good news on the DVD play back issues I was having with my iBook running
    Ubuntu Linux v4.10.

    First I have to type: hdparm -d1 /dev/hdb
    this turns on UDMA2 for my DVD-ROM
    Where would I put this command so it is done automatically at boot up?

    I installed xine-ui instead of totem-xine and now DVDs play smoothly without
    dropping frames. gxine also worked but there is a bug in full screen mode
    that crashes gxine when you switch to full screen. xine-ui doesn't have
    this problem.

    Ok only one more problem to go! =)

    I'm getting a 'popping/clicking' sound when the DVD plays loud sounds. The
    popping occurs over the iBook's speakers and via headphones. I tried
    adjusting the volume but even at low volume I hear audible popping. It
    seems like the audio is clipping. It happens at all volume levels. gxine
    and xine-ui both have this problem. I'm using the ALSA sound modules that
    (I think) emulates OSS?

    There is one weird problem that is also audio related but tolerable:

    The audio during DVD play back is synced with video but the audio seems play
    at a lower frequency. All audio is deeper sounding that it should be. CD
    audio sounds fine.

    Thanks for any help or suggestions!
