same here, although it happened differently for me.

just tried burning a mkv file (1280x688 pixels, so 1.86:1 aspect ratio). Burn correctly converted it to a 720x480 mpg file with very slight letterboxing, which plays at the correct aspect ratio if I open it in quicktime or vlc.

the problem seemed to be at the authoring stage; when the finished dvd was played, the dvd player would treat it as 4:3. I was able to work around by taking the 720x480 mpg produced by Burn, and manually running dvdauthor on it, forcing 16:9 (--video=ntsc+16:9+720xfull).
