Disc burning problem

I have avi files of TV series that I want to put on dis. In the past I have used the old beta version of divx V6 without any problems, easily took 11 episodes to a disc, but now I’m having some problems and not all the files can be played (I did think first off it was a disc problem but one disc played the first 2 eps and not the other) Does anyone know of a program which will let me put multiple episodes to a disc (by which I mean more than just 4 eps which I can do using *********) Thanks
