Brad,
Recording and producing dvds are two different items.
You can record in anything you want.
When you render, render as a standard avi sd format from the timeline.
Then you compress it into mpeg for the dvd. You can compress more to fit more length onto the dvd at the expense of details. Or compress less to qet the best quality.
Normal compression from avi to mpeg is 6mbits for "DVD" quality.
4mbits compression would get you vhs video quality, and 3mbits would get you lp vhs quality.
If you have mostly static images like scenery or powerpoint the 3mbit would not be noticed, but any other time and it would be a degradation.
The second variable you have, is to use double layer DVDs. yes a standard single layer is 4.7gbyte, but a double layer is 8.5
When I put content on DVDs, I do it at 6mbits and get about 2hours 40 minutes on a double layer dvd. About 1 hour and 30 minutes on a single layer dvd.
