If you still have a functioning camcorder, than check out the Dazzle from Pinnacle Systems. This is device that bridges between analog devices and the digital world allowing you to capture your video on the computer. You then can edit if required and burn a DvD. For more information on the Dazzle look here: http://www.bestbuy.com/site/olspage...
This does require your computer to have a DvD burner.
You can also connect straight to a stand alone DvD burner by connecting the A/V (Audio Video) cable from the camcorder to the recorder.
If you have no working camcorder, try finding a used Digital 8. These camcorders generally can play back 8mm and Hi8 tapes and, if your computer has a firewire port, you can capture to your computer using editing software.
Finally, if you are not the “Hands on” type, you can look for a local Dub House. This is a place that does duplications and video conversions. If you can't find one listed in the phone book try calling a local TV station. They usually know where one is.

The environment that the camera will be going into will be pretty dusty and harsh. Any of the Olympus SW series of cameras would be good. The are built to be weather resistant and take great photos.

If you are asking what advantages of buying a main stream name brand....that is Durability, Reliability, track record in the business, developers of new technology and industry standards.
If your asking about Canon vs Sony. Again they are both industry standards and you can't go wrong with either. Sony is a primary manufacture and VERY well known in the Broadcast arena. In fact a lot of competitor equipment have Sony components in them.
Both manufactures are work horses and made to last a very long time.
The Carl Zeiss Lens is famous for the Sony consumer camcorders and Canon lenses are world renown and found on both consumer and professional (including Sony Broadcast) cameras and camcorders.
When it comes to consumer equipment, Sony memory is a bit higher priced than SD and SDHC commonly used in Canon.
Some have noted the colors on Sony camcorders are a bit more vibrant and the focus on Canon a bit soft.

It would be best to take it to your nearest BestBuy and let the Geek Squad take a look. They can advise your of what can be done.
