its my brothers dvd and i cant be botherd plugging the vcr in to copy them onto tape,

the dvd is family guy and as there are 7 eppisodes on 1 dvd which totals 6 gig, i used Smart Ripper to copy 1 of the 25 minitue epidodes which took a 868 meg VOB file theres also a 98k dv2 file/102k IDX file/1k LST/134 kb ifo file

i wanted to see how many episodes i could fit on a 700 meg or 800 cd-r, what have i done wrong or cant it be done (regarding the whole dvd), i thought i might be able to fit the whole series onto at least 2 cdr but im not sure how?
