I have an XP system with a firewire card and a Sony PC5 miniDV cam. When I plug the firewire cable into the cam, XP recognized the camera on occasion but not in awhile. The firewire port works fine for my digital still camera and the camera works fine on my kids Me machine. Does anyone have any insite into this problem? I've tried removing and re-installing the firewire card. That worked for awhile and I thought I was home free, but then and now, nothing. Any insite would be appeciated.

Thanks
