What kind of file are you ending up with? I was guessing an iso file because of the directions given in the link I originally posted:

Step by step instructions for using DVD Imager
1. Use iDVD or some other Video DVD tool to create
A.) a VIDEO_TS folder with muxed video and audio encoded in MPEG2, or
B.)a folder with VIDEO_TS and AUDIO_TS folders and additional files and folders.
2. Launch DVD Imager
3. If you chose option A, be sure that VIDEO_TS folder mode is selected. If you chose option B, be sure that Disk Copy Mode is selected.
4. Drag the VIDEO_TS folder onto either the DVD Imager Dock icon or the DVD Imager window. If you chose Disk Copy Mode (option B), DVD Imager will use the AUDIO_TS folder and additional files and folders found in the same location (folder) as the VIDEO_TS folder.
5. Click "Create Image"..
6. Specify the location where you want the disk image to be placed (if this is the first time you've created a disk image with DVD Imager, or if a checkmark appears in "Prompt for New Location").
7. Enter the name of the DVD using only capital letters and underscores. This is the name that computer users will see when they insert your Video DVD into their computer
8. Wait.

You can now review the Video DVD disk image by using the Finder to mount the .iso image (double click) and DVD Player to play the DVD by specifying the location of the VIDEO_TS folder in the mounted image. You can also burn the image to a blank DVD disk:

Tiger & Panther - Choose "Burn..." from Disk Utility's Images menu, navigate to and select your disk image file.

Jaguar - Choose "Burn Image..." from Disk Copy's File menu, navigate to and select your disk image file.

Are you entering the DVD name in all caps and underscores as mentioned in the directions above?

What version of Mac OS are you using?
