Is there another way

Question

Is there another way of exporting from iMovie using export to Quicktime instead of using the CD option which I use so that I can keep my related chapters so that they show up in Idvd when imported.
Only problem is that the quality is bad and once the DVD is made it plays back in a DVD player in a slow motioned kind of way.
If I use the export to Quicktime full quality settings I loose the chapter settings as they are not saved using this function and this function has better quality.

You don't have to export any of your iMovie projects in order to place them into an iDVD project. And if you don't export, you won't take that quality hit that you've seen.
Create as many iMovie projects as you'd like. In order to place then into one iDVD project, it is recommended that you keep the total length below 120 minutes. That length includes leaving time for the menus that play in your finished DVD, so leave a bit of wiggle room.
When your iMovie projects are complete, Quit iMovie. Launch iDVD and create a new project. Consider which of the iMovies you want to be the dominant movie in your DVD - the one that plays first if the viewer selects "play movie." In iDVD, do File > Import...> Video and select that iMovie project. Your iMovie chapters will be retained and there will be no loss of quality.
To add more movies to the iDVD project, use the little + in the lower left of the iDVD window. If you choose "Add Movie" you can import another iMovie project. It will add a button to your Menu, as well. If that movie has chapter markers, it will automatically get its own "scene selection" submenu based on those chapters.
One thing to keep in mind is that in the final DVD each movie imported from a separate iMovie project will return to the Menu screen after it plays. There is no choice for "play all" where each movie plays in turn before going back to the menu. (If you wanted them to all play sequentially, you could have created them all with one iMovie project.)
Another thing to keep in mind is to check the Map View of your iDVD project as you are working. With multiple movies, you might accidentally nest items that you wanted to place in parallel. That would result in a DVD that is difficult to navigate when viewing. That map also alerts you to missing items on your menus. When your project is finished, be sure to check the Project > Project Info window and be sure that everything checks out, especially the Project Duration. If total time is below 60 minutes you can encode using "Best Performance" and (ironically) you'll get the highest quality video. If the time is between 60 and 120 minutes you must switch the encoding setting to "Best Quality." The closer you get to 120 minutes, the more likely you are to see a degradation in video quality.
Finally, to avoid surprises in your burned DVD, don't let iDVD do the actual burning. Instead, do File > Save as Disc Image. That lets iDVD do all the encoding, rendering, compressing. When done, you'll have a disc image file that you can preview in your DVD Player Application. If it plays properly, you can burn the disc image to DVD using Disk Utility or Toast. Reducing the speed of the burn to as slow as your media will allow can improve playability.
