    dma is on, dvd playback still lacking

    Hey

    From what I can see in my hdparm.conf file, my drive has dma = on, and yet my video still seems to be unnaturally unwatchable. I watch music dvds by the way, and it's hard to explain but the video is just slow and painful to watch. I don't know what to do.

    I've played around with video settings in vlc, and in movie player etc and it all doesn't work.

    Suggestions (please)?

    Re: dma is on, dvd playback still lacking

    My dvd rom is /dev/scd0, which means it is scsi from what I understand. Apparently hdparm does not work on scsi drives, so dma being enabled is not really an issue.

    I've read that my xserver.xorg is configured wrong, and that I should run:
    "sudo dpkg-reconfigure xserver-xorg"

    And this is what I saw written in the same thread I obtained this info:
    "Very good news! I'm able to play DVD.

    and this was not a DMA issue!!!

    In fact I have an ATI Radeon card and the DRI was not enabled. I removed all the fglrx drivers, re-installed the ATI driver as well as the restricted kernel module for ATI and it works!"

    I have an nvidia geforce fx 5200, with the latest drivers etc. Where does my problem lie, what do I have to do to get my dvd video working correctly?

    Re: dma is on, dvd playback still lacking

    Do I need to edit my /etc/modules file with anything? Is that needed for what I'm looking for?

    I've heard it might be because speed from drive to system is slow, is there a way to tweak that?

    And sdparm.. what is it, should I use it, will it be of any help?

    Take one step back from the keyboard and take a deep breath.

    Okay, you feel refreshed? Now let's get started.

    1) this is either a video card conf issue or a faulty drive.
    2) I will show you the tests, you run them.

    First let's test the video.


    Code:
    $ glxgears -info
    Collect the following info.
    GL_RENDERER = ???
    GL_VERSION = ???
    GL_VENDOR = ???
    GL_EXTENSIONS = ???


    At the bottom of the screen you should see something like this:
    2782 frames in 5.0 seconds = 552.702 FPS

    let it run for at LEAST 5 lines, collect that info.

    Okay with that, do you have a XviD or Divx5 encoded file, the length should be at least 10 mins. Play that file and report back on quality. Does it lag? Does it should right? etc.

    Next testing the drive.

    Next test, put in a Audio CD and listen to it. Does the audio should good? Does the music skip?

    And the finally test, put in a data CD. Anything with over 100MB, copy the contents of the data cd to a folder on your Hard Disk, you can delete what you copied. Does it copy correctly? How long did it take? etc.

    I played a 70MB xvid video file perfectly all the way through.

    Audio cd works fine.

    148.5MB of data copied to harddrive in around 2 minutes, copied correctly.

    Re: dma is on, dvd playback still lacking

    Okay the good news is. 1-You card is fine 2-the drive is fine.
    So now we are looking at a software issue.
    To bypass any mis-understanding.
    From console, run the following. and copy and paste the output BEFORE you press "Y".

    $ apt-get install vlc vlc-plugin-*

    I will be watching the forums for the next hour.
