You can mount the 9700 as a logical drive (device and MicroSD card) and simply drag and drop your video from the BB to your PC hard drive when connected by the USB cable.
You might find it best to set the BB to automatically appear in Windows Explorer -- on the 9700, in Options > Memory, set the Media Card Support and Mass Storage Mode Support to 'On' and Auto Enable Mass Storage Mode When Connected to 'Yes' and you should be good to go. Plug the BB into the PC and check out Explorer for the newly recognized drives.
BTW I always "Eject" the BB drives before unplugging the device. There are stories of frying the SD card if not always doing this.
