I've seen on occasion posts concerning dropped frames using 1394 firewire. I use a digital Sony camcorder, Adobe Premiere 6.5, and WinXP, but have yet to experience problems with dropped frames...until last night.
Adobe's support page has some suggestions concerning this problem, which I think can be quite helpful. Others have posted similiar suggestions in this forum. For reference, the Adobe Premiere support page is
However, none of the suggestions solved my problem. On a whim, I inspected the Image Devices in the Device Manager. Scanner and webcam were listed, along with the Sony camcorder. I found that if I disconnected both the scanner and webcam, then rebooted, the dropped frame problem went away. Simply disconnecting did not work, a reboot was needed.
Not sure why this is the case, as both are USB devices and the Sony is 1394, but given that they were all listed under Image Devices, I figured why not give it a shot anyway. This may not help you with your problem, but it may be worth investigating if you have issues with dropped frames.
