None of this address's the fact that richardnovak77 started off asking about FILM resolution, not DVD resolution. If in fact he's sending to FILM, then he should talk to his Telecine service. If in fact he's outputting for DVD, then the 720x540 figure would be fine for 4x3 imagry. For footage that is 16x9 going to DVD as LETTERBOXED, then output as 540x304. Since a DVD does 16x9 letterboxed as black borders above and below a 16x9 image CENTERED inside a 4x3 overall MPEG2 file @ 720x480. For footage that is intended for 16x9 ANAMORPHIC DVD, then output as 1440x720. This is 1280x720 (16x9) with the extra pixel width for the square VS rectangular pixel problem. Hope this helps!! :D
