When You Share to Media Browser in iMovie - WHAT resolution do You select ?
iDVD need - MEDIUM or ev. Large - Not HD or any of the others as resulting DVD if any will be bad (far from optimal)
Best quality You can get is by using a Video-Editing program that handles interlaced Video
• iMovie'08 or 09 or 11 - DON'T
• iMovie up to HD6 - Does so
• FinalCut any version - does this too
This is due to DVD as Standard - it is and can not be any better than - interlaced SD-Video Quality
