how can i stick more movies onto one dvd disk?

i have recently attained a movie season. each episode is 350 mbs, there are 20 episodes. vcd will only allow me to have if lucky, 2 episodes on one disk. dvd will also only allow 2 episodes on one dvd disk using VSO ConvertXtoDVD. What i was hoping is to stick more on one disk, not lose any quality (picture and sound) and still be able to read it on my dvd player... Is this possible?

anybody?
