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!
