Force dvd to output 16x9

[Guest]

hey,
i´m doing an all grafix projekt in AE (Dvx footage must be added later...) in an PAL 16x9 comp and i want to output it to DVD.
First, what is the best way to create an DVD mpeg file out of AE, second how can i force the DVD to autostart, have 16x9 a.r. and loop?
will use either pinnacle edition or iDVD for DVD output... :-/

btw,
started this as a PalD1/DV Widescreen projekt in Photoshop, AE recognizes it as widescreen but i have to check pixel aspect ratio correction (i translated this, don't know if thats the term in english :)...) to display correctly...
is this the correct setting for doing 16x9 projects...?
