I am using a Dazzle 80 video capture device USB, to capture some video and edit out short clips into mpegs. I notice that audio and video do not synch up properly except for in lower quality settings. Is something causing it to lag, I am doing all the work on a homebuilt Pentium 4 2ghz PC (Asus p4s333) with 512 megs of pc 2700 ram, and a seagate barracuda 7200 rpm ATA 100 drive, I am assuming that this should have more then enough power to capture video. Could it be the USB device capturing the video and audio causing the lag, its only USB 1.1 so it isn't incredibly fast. Would I be better off switching to a internal card like a pci ATI tv wonder or all in wonder agp and capture the audio with the sound card?
