Newbie q - How to format a CDRW

Can anyone please tell me how to format a CDRW? I have one that was pre-formatted for Direct CD but i cannot use it on NERO to burn asf movies?

Also, how would i burn asf movies using nero on CDRW after i format so i can play it in normal CDs.

Please help or if you know of any site that has this info. Thank you so much

in nero, goto the selection ‘cd-recorder’ on the menubar. select 'erase cd-rewritable.

as for the movie thing, you would need some kind of file converter, because video cds can only be made from MPEG movies.
