Disk Utility is great, I use it all the time, but we all know it doesn't make Pro. Menus. I agree quality can be poor depending on the source format. My Solution is VisualHub. When I made my first erroneous DVD (funny glitch in the Video, good audio though) I read somewhere that iDVD's 'favorite' source format is DV (NTSC, PAL). IF you have large hard drives, then use VisualHub to convert 'your' .avi/misc. video to DV (about 30 minutes for a standard movie). A 1.8Gb .avi movie turns into around 17Gb! Then use the DV in iDVD and burn the .img (iDVD/finder/file/save as image). Test it. And get rid of that giant DV. Then you can burn as many copies as you like with DiskUtility.
