I own an HP Desktop Pavilion that I bought a year ago. I installed this product with no problems by opening up my PC, inserting the PCI card, connecting the power to the PCI card, booting up my PC, and then installing the appropriate driver. I have the Windows 98 Second Edition operating system on my PC.Then I hooked up my Sony DCR TRV 33 mini DV camcorder, of course using the firewire interface. The ActionTec PCI card failed to recognize the camera. ... the cable provided with the product was bad. ... I will never purchase another product from ActionTec again.
