The laptop I purchased this summer did not come with a firewire, so this card was a necessary part of getting my home video onto DVDs. Some of these cards are very pricey, so I was skeptical when I saw this for such a deal. However, I plugged it in, and it easily located it's own drivers - both for the expresscard, AND for my DV camcorder. The best part? Even with upgrading parts of the old computer, the captured video was often unstable, pixelated, with dropped frames. Not so here! I recognize that this actually has a lot more to do with the new computer, but it was a pleasant surprise to find this expresscard did work just as it should. And it DOES come with it's own cable.
For those who need these details - I use a Windows-based laptop running Vista. I also tried using the video software that Windows includes - Movie Maker to import and edit, DVD Maker to burn. I'm pleased with Movie Maker - simple, streamlined, and fairly intuitive. Not so impressed with DVD Maker, but that's another story!
I do not have an external hard drive, so I can't comment on how well this expresscard handles those. But for DV camcorders, save yourself some $ and buy this!
