    dvd skipping

    Sorry if this has been addressed before; I looked a lot online and searched here, found nothing so far.

    I have an odd problem with DVDs. They start out fine -- low CPU usage, movie plays without problems. Every couple minutes, though, CPU usage jumps a bit, more or less in steps (not very gradual). Eventually it reaches 100%, and soon afterwards the movie starts skipping to the point of being unwatchable.

    I've tried the "hdparm -d1 /dev/dvd" trick, it doesn't help at all. I not even sure if this is a problem with my DVD drive, or the software. Basically, I'm not even sure where to start asking questions. Anyone have any clue?

    Try this link. I think it came down to optimum order for loading modules.

    Thanks, drakebasher. I took a look at that link and the "answer here" link on that page, which had to do with reordering the modules. But I don't have an /etc/modules file. I have an /etc/modprobe.conf, but it looks quite different:

    options snd-intel8x0 index=0
    remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
    alias usb-controller ehci-hcd
    alias usb-controller1 uhci-hcd
    That page also had a link to this, which suggested modifying /etc/hdparm.conf, another file that I don't have.

    To clarify, turning dma seems to work fine:
    # hdparm -d1 /dev/dvd
     setting using_dma to 1 (on)
     using_dma    =  1 (on)
    So I'm still lost :( I also find it weird that the choppyness only comes after a few minutes, which I haven't found as a specific symptom anywhere else.
