How are you encoding this finished file?
If you edit 16X9 project, export as current settings – reference file.
Drop clip into compressor to make dvd files, check for 16X9 and import into I-DVD
(We use DVDSP, not familiar w/ IDVD…)
OR
Import file direct into Idvd.
Before u import anything, check your Idvd project settings and make sure they’re set to 16X9
After you put in your clip make sure u have 16X9 pan and scan set to display you video. This will flag DVD players to display it properly.
Hope this helps.
