From what I can see, you should be good to go with editing. Be warned that DVD-based camcorders do not allow for very good quality editing.
For DVD-based camcorders, *typically*...
When the video is captured to the miniDVD, you might need to "finalize it before any other DVD player will be able to use that disc. Please refer to your manual.
You will also need to install a DVD ripper. Google that term. You should get a lot of hits... Pick one. I use HandBrake. I heard there is a Windows version out there.
When the disc is ready, remove the disc from the camera and load it on the drawer loading optical drive you have. Close the drawer.
Launch the DVD ripper. (If your DVD player automatically launches, quit out of it. You cannot do anything with the files on the DVD disc from the camera - you need to rip the video and audio... just like ripping sings from a CD.)
Select the "scenes" or file clips you want to rip. Save them all to a folder somewhere on your computer's hard drive. When all the files/scenes you want are ripped from the DVD and in the folder you made, quit the DVD ripper. Remove the disc and store in a cool, dry place in its case. If the disc and the case are not already marked (contents), do that.
A word of warning: There are a LOT of posts from people who (1) could not get their PC to recognize the disc, (2) had problems with video quality and (3) needed to get "ISObuster" to get to their video from these DVDs.
Launch your video editing application. Import or open the video files you just ripped using that application... Edit. Save.
When editing is complete, do whatever you need to do to burn a DVD or save the file in a format you want. You can save it as an AVI to a data-DVD is you want.
In the case of a hard drive based camcorder, it is connected using a USB cable to the computer - and the camera's hard drive mounts like any other USB mass-storage device. The video clips are copied to the computer's hard drive as you would copy any other file. Save. Edit. etc...
In the case of a miniDV tape, based camcorder, it is connected using a FireWire cable to the computer - and the camera is controlled by the computer's video editing application. The video is imported from the tape to the computer right into the editing application. Save. Edit. etc...
