I am wondering, though, if it is designed specifically with DivX specifications in mind. For a 1 hour 40 minute clip such as that used in the example on the link page you gave, and using Dolby or mpeg layer 2 audio at a higher bitrate than the 160 kbps given in the sample, you could burn all that to a single layer DVD as mpeg-2 with a bitrate closer to 6000 kbps, which would even give you good quality.
If you set it as low as that sample figure (1752 kbps) it would be impossibly poor quality, but you could fit more than 4 hours on a DVD...

Again, I am talking about DVD-compatible mpeg-2, not DivX which of course uses much lower bitrates, but produces high quality video. You can of course burn it to DVD, not not a typical video DVD -- just as an archive disk. But you need a stand-alone DVD player which is rated to play DivX discs -- though thankfully, there are quite a lot of those on the market these days...
