I've been using different types of Sony handycam camcorders. I just bought the dcr hc 36, and the problem is that my firewire which I've been using and works fine with the other camcorders, cannot detect it. I'm using Win XP SP2. Ive had tried a lot of things, such as running the "regsvr32 %windir%\system32\qdv.dll" command, but windows still cannot detect the camcorder. Please help.
