I have read posts where 16:9 versus 4:3 issues are dismissed as incorrect DVD player settings, etc.
I think there is a real bug in how 16:9 is handled in the MyDVD/Videowave products, where they should be set to Anamorphic display, that is one can select 4:3 P&S, 4:3 Letterbox, or 16:9 display, and the display should be appropriate to that setting.
My DVD players: OPPO, Sony RDX300, Panasonic DMR ES10, Cyberhome
I have created DVDs using MyDVD9 and VideoWave. The above, and most DVD players have settings for 4:3 P&S, 4:3 Letterbox and 16:9. Only DVDs I have created using MyDVD do not respect the 4:3 Letterbox setting, all my other DVDs show up in 4:3 Letterbox format - the MyDVD created DVDs treat 4:3 P&S and Letterbox as the same setting. This seems to me to be a flaw in the MyDVD (VideoWave product).
