"Tip: If you are asking for help to troubleshoot a computer-related problem, please be sure to include all the necessary information (ie: operating system, model number, hardware, software, etc) that will help others identify your problem for a speedy resolution."
You ignored the tip and as such I can't tell if your PC should work with such. For instance, what you write would be proper for many PCs that XP is installed on because the person who installed XP didn't install motherboard drivers, have a current BIOS or played with the BIOS settings. Some will tinker with plug and play services or firewall the machine to the point that many things just fail.
Your post left out the PC details and more.
I am unable to get Windows XP to recognize my camcorder at all through firewire. When I plug in my Sony DCR-TRV38 and turn it to VCR to try and capture, absolutely nothing happens. There is no change in device manager at all. I have replaced the firewire card and the firewire cable, and still no change. Any suggestions you have are greatly appreciated. Thank you very much.
