My problem is the driver for the panasonic camcorder model pv-dv900.

I've learned my lesson and will share it. Use firewire and try WinDV. Best of luck.

You don't need a driver. Just connect the camera using the cable provided with it; turn the camera on and set it to play movies. The first time it will upload the necessary drivers. THen, use Windows movie maker (it's included in vista, my version at least) to import the movie (if you don't find it, click on the start button and type "movie" on the search box). It's much better than the crappy software provided by panasonic anyways.
