Built in Fire-wire port vs. Capture Card

I have 2 built-in Firewire Ports on my Desktop and use it to capture footage from my GL-2 to my harddrive.

When I play the video off of my GL-2 on the TV or the Capture Window on Adobe Premiere Pro, the video is smooth and looks fine and no frames are dropped.

However, after the capture has taken place, when I play the video, I notice that there are some occassional jumps (maybe 1 frame here and there like every 30 seconds).

What is this a function of? My firewire port? Would a Capture Card eliminate this problem?

What use is a Capture Card if one has a couple of Firewire Ports already in their computer?

You don't say whether you're capturing to a separate drive or your system drive. If the latter, that is likely the problem. The O/S makes too many calls on the hard drive for it to reliably capture a constant stream at 3.5 MBps.

Today's SD capture cards (DV25) mainly offer more and faster effects processing in real time. Some add hardware encoding. But modern PCs have so much more muscle than those of only a few years ago that software editing without a separate card is becoming increasingly prevalent.

I had the same problem with playback in Premiere Pro until I added another drive. Now my "system drive" is just that and my video goes on two other drives. Also, you might find help by reading some of the stuff at http://www.videoguys.com/. Since I went through some suggested XP fixes and tweaks you'll find there and separated my video files from the system drive I've had no other issues with choppy playback.

the latest situation

what is occuring now is any video file that I record can be played back on C: (system) as well as all USB storage devices, however if that same video is placed on a (non C:) internal harddrive, it won't play regardless of which drive (including an internal harddrive) captured the video file.

this same video file will play choppy off of adobe premiere, however it will play just fine using WINDVD or another DVD player.

i checked out the videoguys.com website. which specific recommendation (there are so many) do u think fixed the choppy problem?

The links along the left side of the page, namely
http://www.videoguys.com/system.htm
http://www.videoguys.com/WinXP.html and
http://www.videoguys.com/Top10tech.htm.

I've learned a lot here on this forum and other places like Videoguys. I know there's tons more to learn but this will give you a good clean start with your system, something I didn't benefit from which caused some headaches.
