I am using a capture device, dazzle dvc80 with pinnacle 9.4 and movie maker 2,I disable all in system tray and most processes I am familiar with in task manager and set cpu usage to realtime for either one. I still get patchy or stuttering of the capture. Either voice or picture is out of sync. I use usb2 connection, windows xp home ,amd duron 1.3, 512 ram, 80gig hd. I have reinstalled usb2 drivers, and all else is updated. antivirus and spyware programs all updated and no detection found. HElP!!! Any help is appreciated,Thanks
