The DCRTRV27 can connect to a PC by using either a USB or firewire cable. If you want the best video use the firewire 4 to 6 pin cable.
You can output the video as raw, then convert the video to any number of mpeg formats by using either Microsoft's Movie Maker 2.0, it's free, or the software that came with your camera.
The video can be burned to CD, but this is not a very good choice since even the most modest video can easly exceed a gig in size.
