All versions of iMovie have

options to create different files with different compression amounts and different levels of video quality.

For example, in iMovie '09, under "Share" on the command line,
select "Export using QuickTime"
in the Export Dropdown, select "Movie to QuickTime movie"
Click "Options"
In the video portion of the dialog box, click "Settings" and pick the compression type (I like h.264) and be sure the slider for Quality is high and click OK
then click Size at the dialog box and select 1280x720 or 1280x1080 and deinterlace - then click OK and click OK again.
Name the file and select the destination. Click Save. The rendering time will vary based on the options you selected and the configuration of your computer (CPU, RAM, etc). It would be best if you tried a small video file first to be sure you have the settings you want, then go for longer video files. Rendering can take time. This is not a Macintosh issue - this is a physics issue and can impact all computers rendering high definition video files.

iMovie does not "export to DVD". iMovie has a button to burn a DVD that causes iDVD to launch. ANY DVD authoring application will downsample to what its DVD burner can handle - in this case, your computer's DVD burner is standard definition only. The VOB file will be downsampled and burned to DVD so it can be played in a regular DVD player. Regular DVD players cannot deal with high definition video files.

If you want to move the video data file from computer to another, you can set up an AppleShare network or you can burn a data DVD as Bob instructed. Using the file created in the Movie to QuickTime Movie above, insert a blank DVD. Let it mount to the Finder. Drag the QuickTime file to the blank DVD. It will copy. Open the hard drive. Click once on the DVD file name and name the DVD. in the hard drive window, there will be a black and yellow ball next to the DVD with the QuickTime movie you just copied to the blank. Click the black and yellow ball to burn the file to the disc.

Since we cannot see what you see we have no idea what constitutes poor quality, but with the basics you are working with, iMovie and iDVD, downsampling to standard definition video is expected. If you want high definition video to play in a Blu Ray player then the easy way is to get a BluRay burner (LaCie makes good ones) attached to your Mac and use a more robust editor like Final Cut (Express or Pro). If you want high definition video in a computer-readable format (in a MOV or AVI extension file type), then use the data file method and do not use iMovie's burn-to-DVD function or iDVD...
