Widescreen DVD issues

Okay, I have taken my film from After Effects to premiere pro with the adobe dynamic link, and have been trying to get it onto a dvd using encore. The problem is, the dvd will look wonderful in its widescreen format, but only if the dvd player is set to 4:3! If the player is changed to widescreen, my video appears 4:3!

-The original video is 1440x1080 @ 25fps with a Pixel Aspect Ratio: 1.333

-The Premiere project is HDV 1080i 25 1440x1080 (@ 16:9), with HD Anamorphic 1080(1.33)as my pixel aspect ratio.

-The After Effects project is set to the exact same settings as the premiere project, without locking the pixel aspect to 4:3, and using HDV 1080/DVCPRO HD 720 (1.33) as my aspect ration.

-The Premiere export to encores settings are PAL 720x576 @25fps with the widescreen option selected

So again, when the dvd with these settings is played, it will play in widescreen only if the dvd player is set @ 4:3. Setting at widescreen makes it play in 4:3. Im sure its something small/simple, but i really need the video to play in widescreen automatically. (And setting the premiere export to encore as 4:3 instead of widescreen doesnt fix it, just makes it letterboxish

Sorry for such a detailed question, but im getting desperate

Thanks!
