Dropping frames on capture AFTER upgrade

Discussion in 'Amateur Video Production' started by Lister Monocle, Jul 17, 2003.

  1. Previous system was Athlon 1ghz, 512mb pc100, ecs motherboard, Aver
    SteroTV card. Using Virtualdub, I could capture 640x480 29.97fps with
    MJPEG quality 20 with zero frames dropped.

    I've now upgraded the mobo to Asus A7N8X, CPU to Athlon 2600xp, and
    memory to 512 pc2700 ddr. All other components are the same. With all
    the same settings, I now drop a frame every few seconds. CPU usage
    never goes above 30% or so in Virtualdub or Task Manager. Hard drives
    are the same as before, UDMA enabled, and HD Tach shows they're
    performing up to speed. Nothing else is running, it doesn't matter
    what resolution, codecs, compression, etc I use, frames are always
    dropped.

    I thought it might be bad VHS, but it does it with TV source as well,
    or even with video input to card disconnected. Yes, even with a blank
    blue screen and no audio, I still lose frames. I'm losing my mind
    here.
