    k9copy - stuttering playback! can anyone help???

    Hoping someone can help. I am using k9copy to rip and burn some of my DVD's.

    I get no errors while ripping and burning and everything seems fine. But the resultant iso file when you play it back jumps or stutters every 5 seconds or so.

    Is there something I need to do with the settings or is it a pc problem. I have an Acer Aspire 7730 with bags of memory.

    Any advice would be appreciated.

    I'm trying to remember but I thought I had a stuttering problem but I believe it was an audio problem. In VLC I had to Set the Output module in the Audio to ALSA from Pulse with the show settings on all.

    Try using a different player like VLC, mplayer to see if its all or just related to the player you are using.

    Are you playing the actual ISO file in a computer video player?
    Or are you saying the burned ISO file skips in a standalone player?
    Use K9copy to create the ISO.
    Use VLC to play the ISO to see it before you burn it.
    I would use K3b to burn the disc, Verbatium , of course.
    Sometimes the disc playback in Linux can be jumpy, try a stand alone player or Windows computer to watch the disc you created.

    I am comfused. Are you copying video or audio? Audio CDs should contain CDDA (Compact Disk Digital Audio) files rather than an iso. I haven't tried burning an audio DVD, so I am not sure what you are copying.

    Anyhow, your burn speed may be the problem. Whenever burning a DVD (or CD), always use the slowest setting the burning app will allow. You will end up with many frisbees burning at the fastest speed.

    I have exactly the same problem, and I didn't solve it despite many tests changing all possible parameters and many googling...!

    I have Ubuntu 12.04, 2Mb ram and dual core CPU. If I play with Totem or VLC I see the stuttering, audio seems to be in syncro. Stuttering persists if I play externally with stand alone players.

    Still searching for a solution... any suggestions that you think may be useful to solve this is appreciated.
