DVD question...Help!!!!

Hi all, probably a silly newbie question. I burned a dvd thru my dvd recorder (panasonic e20) of some old family 8mm movies. I would now like to extract stills from the dvd into my ibook thru the dvd. Is this possible? The dvd player doesn't seem to have a screen capture feature. Also, can I convert portions of the dvd into a QT movie? Any help would be really appreciated. I'm a little over my head on this one. THANKS!
