I have final cut express and was able to import my full HD video into FCE but I now need to burn it to a DVD (BR on regular DVD that is). I want it to stay as 1080 and no be downgraded. Any thoughts on ways to do this?

Other details:
1. I also have Toast Titanium 9 with the BluRay/HD support plug in.
2. Sony HDR-SR11 Cam recorder (1090i)
3. Don't have a Blu Ray burner yet.
4. Just want to get family movies captures on cheaper DVD and DVDDL for now. Later one prices come down I'll switch to real Blu Ray discs.

Any thoughts or help is approcated.
