can you use iphone material in FCP 7?

hay,

i am importing material from Iphone 5 into FCP 7.0.3, but is needs a lot of renderign. now i have tried apple pro res. but i only use it for ineternt or to make a dvd.

and for anonther project I mix material from iphone with dv, from a card (Sony camera VXE), etc, so it s a lot of different material.

I tried to make a dvd, but on some dvd players the dv material gives jittery images. Which codec can I use the best?

apple pro res? or apple pro res Lt?

or....

thanks.eva
