Codec for DVD Studio pro (Mpeg-2 gone)

Hello Final cut guru's.

I use to export codec Mpeg-2 and dvd studio pro worked like a charm. I now upgraded to Final cut studio (Version 5) and no Mpeg-2 codec anymore it's not an option. I'm trying new codecs an get pixelation please help me i don't know which codec to use. and if there is a website tutorial for the new final cut studio and dvd studio 4 codec for sd dvd's please help. is there a way to get the mpeg-2 codec back even? HELP!!!

you are now supposed to use "export to compressor" and you'll find mpeg 2 there.

OR

just export a reference movie from fcp and let dvdspro make the mpeg2 for itself
