Final Cut Studio aspect ratio help

Hello. Well first off this is my first time using final cut to put together a video that Im making. Heres my problem: I imported my video from my panasonic mini DV camera which defaults to 16:9. It imported into final cut like that but then when I went to export my sequence to compressor to compress it to the correct size and format (with chapter markers so that DVD studio will recognize them) it changed it to 4:3 for some strange reason. In doing this I had followed all of the tutorials on apples website for FCS so Im not sure where I went wrong. Is there some type of setting in final cut that I need to set in order for it to be exported in 16:9 versus 4:3?
