Action Safe and Title safe are there for you when desinging effects and grfx with regards to TV Broadcast and display.
If you have unwanted junk in the shot, that should have been caught on set.
You’ll need to zoom in on those shots until the unwanted goes off screen or matte it out as suggested.
Resing up your SD to HD will degrade it far worse then squeezing it on a Single Layer DVD.
120 minutes and less will go on a SD DVD just fine.
Re-encode, lower your bit rate some, Keep doing it until you land around 4.2GB for the vid track, it’ll look fine.
