Can't copy files onto DVD

I've been using divx to dvd to convert my files and copy to dvd to burn them with....I've been trying to burn 4 episodes of a series but everytime I do there's only one episode on the dvd....I've added all 4 folders and it still doesn't work....I've also tried converting all 4 files into one but that doesn't work either and I've also tried nero but that doesn't work either...I've wasted several dvd's trying to fix this so does anyone know whats causing this? or anyone other programs I could use?

 

First of all to play in a DVD player the files must be encoded into MPEG2 format. MPEG2 can get to be a tad big, which sometimes would only allow one video.

When I tried to convert Yu Yu Hakusho to DVD I could only fit roughly 2-3 episodes on a 4.7 GB disk. Ofcourse thats for DVD format, but if i were just saving to data, the OGMs are only about 200-300 mb.

In english: DivX is more compressed. When converting to a DVD format like MPEG2 the filesize grows.
