I used Premiere 6.5 set in NTSC widescreen for a project. When I burned it to DVD straight from Premiere, it put the whole thing in 4:3 with a border of unused screen real estate all around it. When I exported it as a movie for burning w/ Nero, It was widescreen, mostly. At every transition (cross disolve), the video would drop to 4:3 then return to widescreen past the transition. I also had still images between major sections & they always viewed as larger than the rest of the video in either version (filled the whole screen). I am confused. Anybody got any ideas on why & how to fix it?
