A DVD blank can hold 60 minutes of video and/or less then 4.6 gigs of data. As long as your divx conversions are below both of those threshholds, you should be fine.
Are you looking to just backup the Divx files? If so then the 4.6 gig is the limitation you will need to be concerned about. If all your videos are larger then 4.6, you will need to spread them out onto multiple DVD blanks. That would be my recommendation rather then reconverting them to a smaller size to get multiple on one DVD. DVD blanks are becoming very cheap. In big-box stores (Best Buy, Circuit City, etc.) I can buy 50 DVD blanks for $20.
Are you looking to make them watchable on a regular DVD player? Well, then you will run into some problems. Most DVD players will not read a DivX DVD. You might want to consider a coversion to VCD or SVCD which will play in a majority of DVD players.

That was the site I was directed to when first getting into video creation a couple years ago.
Hope that helps. If you have specific questions please feel free to ask.

These files are already on my computer as DivX format. MyDVD saids there 8.67 gigs. I was wondering if theres a way to shrink, or convert them to a different format, so all of them fit on one 120 minute 4.7 gb DVD-r

Well, can it be done - yes. However there will be tremendous loss of quality. You will need to take something like Nandub and recompress the files using a tighter compression scheme; this means loss of quality.
There may be other ways but none that I am aware of. Again, I would suggest http://www.vcdhelp.com They have a very good forum where you can post questions. One of their experts might be able to point you in a better direction.

I am no expert, but I will give you what I beleive to be true. When I buy a spindle of disks they always say that you can handle 60 minutes in SP mode and 120 in LP mode. I have never tried to get more the 60 minutes on a disk so I have not explored how to do the 120 method. From the label it seems like it can be done - I am just not sure how. I have 3 different programs I can use when I burn, the most advanced being Nero. I would assume there is box I can check or menu item to pick. I am away from my main computer but I will see if I can find out any information.

(PS - I got that book you recommended. Excellent book. I am enjoying reading it. Last week I was reading it while waiting in lines at Disneyland. My biggest problem is my G1; it has a max f-stop of 8. I might need to upgrade to a new digital camera sometime in the next year.)

6. How many minutes of video can I burn on one DVD?
By decreasing the bitrate you will be able to burn up to 360 minutes on one DVD.
Quality Recording time
High Quality 60 min
Standard Play 120 min
Long Play 180 min
I found this on Google:

They point to a web site dvdshrink.org but that is mainly about getting more then 120 on a disk.

With MPEG2 you can actually get as much as 2 hours on a stardard DVD-R/+R. If you're starting with a good quality digital video source and a decent encoder you're not likely to notice much of a quality difference between between compressing it so 1 hours fits or 2 hours fit.
The one thing that can get in the way of achieving this is the audio encoding on the disc. Typically when I want to keep good video quality up to 2 hours, I need to do some work on the audio to compress that so it doesn't take up so much space. In my case I compress the audio into a Dolby Digital track which is much smaller than the normal uncompressed PCM audio format that would come out of the MPEG compressor.
I wouldn`t recommend burning more than one hour to a single layer DVD. As RU42 said above, the quality WILL suffer, and it does. I burnt a 2 hour disc, found the quality lousy (and I don`t have cheap gear) so reburnt onto 2 lots of 60 minute DVD`s and subjectively the imrpovement was over 100%..
