I've been contemplating buying a DVD burner and one use of it would be to backup dvds that i purchase, i've had a few 'walk-off' recently that i'm none to happy about.
my impression is that most video DVDs weigh in at about 6GB, is that right?
Is there a significant number of DVDs that are less than 4.7GB (or whatever the size of a blank disc is)?
thanks in advance.

The only DVD that I have that is less than 4.7 GB is Citizen Kane, which is B&W.

10GB is the most you'll ever need. Dual-layered discs hold 9.8 GB, the rest is padding in case you need it.
Most, if not all DVDs nowadays are dual-layered.
You could use some of those shrinking tools to strip what you don't need from a DVD and recompress it.
However, if you just take care of them like I do, you'll never have to back up anything except the TRULY rare DVDs.

It takes so much time to recompress a DVD to fit on a DVD-R (not to mention the reduction in quality) that it's not worth it. Just buy another copy if you care that much.

On my 2.53 GHz P4 it takes about 22 minutes.

DVD-R - 4.38 GB
Average commercial DVD - about 7 GB or so.

DVD9-->DVD5 technology has changed a lot in the last couple of years. It doesn't take long on my TiBook, with excellent quality. Today's software doesn't re-encode. The software just throws out frames, but it works great.
Not that I bother though.

I do it to make backups of the Disney flicks for the kids. It's all one-click-and-walk-away now.
