DVD SP (or any good DVD authoring software) without the whole FCP package?
 

I am about to give up on iDVD, and would like to check out DVD SP -- but I've been working happily in Final Cut Express for years and don't feel I need FCP -- and I certainly don't need to spend the $1000 on FCP just to get the DVD authoring software. Is there any good DVD software out there that is possible to get without buying a whole new video editing package?

thanks,
