As mentioned, DVDA will let you know what it's best guess is at the project size - however, DVDA is really, really bad at guessing, especially if you had a motion menu or an animated thumbnail or 2. I've never seen DVDA underestimate though, only over. So if DVDA says you're over 4.7, then the best thing to do is just do a prepare only, then check the size of all the files generated, if Windows says the total size is 4.37 or less, you're good to go.

I've not played with animated gif's, but my memory is that Vegas will only read the first frame. Anyway, if I had something like a motion menu that I wanted to create, I would do most of the work in Vegas and then render it out as an mpeg to be used as the background video.

Once in DVDA, click on File -> Optimize. It will show you the sizes of various files and what percent of your DVD will be filled.

If you encode outside of DVDA (for example, in Vegas), use this bitrate calculator to find the bitrate for your MPEG-2 file that will make your project fit a single DVD:

Bitrate Calculator

Thanks for the reply guys.
In that bitrate calculator:
what is the best setting for audio bitrate?

Are there any nice tutorials for DVD-A?
