the newer ones will burn both +/-R
ya, as noted above, slap in a DVD and you'll eventually see an icon come up called "Untitled DVD.fpbf"
what i do is open a finder window and find the files i want burned and drag them over to the icon (you'll also see the icon in the finder window and can also drag to it)..
when i have everything i want copied dragged i hilite the icon in the window and it shows me a "Burn" button.....click that, rename if desired in the new pop-up window and yer rockin'
EDIT: damn, it only showed a few replies when i posted this..
all this work for nuttin'
