16:9 vs 2.35 vs 4:3 – answer is YES, you MUST have LARGE black bars on 4:3 TVs
on 16:9 TVs you have small black bars 🙂
Please check your encode settings and track settings – you must set “16:9 MPEG2” in source/target and to 16:9 Letterbox in DVDSP
what is 23.976->29.97? Ohh… DVD can’t be progressive, and YES in 23.976 footage will be added fields for 29.97 interlaced video, it’s all right
