You might want to take the project to a video shop and have a pro do it. You have a month or two learning curve and a significant cash outlay ahead of you to go from no digital video experience to doing film transfers, audio mixing, video editing and dvd authoring.
For the film transfer to digital video, the pro shop will have a film projector with a very short focal distance lens, a film transfer box (this is a ground glass rear projection 'screen' and a first surface reversing mirror) and a mini-DV digital video camera to capture the screen contents. You can sometimes find transfer boxes on ebay.com. Some even have the projector built in. Won't be cheap and you'll need time to learn how to best use it.
Once the film is in digital form it will need to be transfered to the PC though a firewire interface. This also needs a large capacity hard drive and preferably NTFS format, since FAT32 format has a 4G byte file size limit. Windows XP has NTFS format. 4G bytes is about 16 minutes of mini-DV.
Then the digital editing, audio mixing and final compression to MPEG2 DVD standards can begin. A good video editing program can handle this. They range in price from fifty to several thousand dollars. The cheap ones will let you do the basics and a few special effects. The costly ones have more special effects. All of them will take a lot of time for proficient use.
When that is done, the next step is to create all the DVD menu's, chapter marks and action links. Some video editing software can do this too.
