Assuming the avi movies are in divx format, converting them to DVD video iso is very time consuming. I never used movie clone 4 before.
If your DVD player is divx certified, then it's easier. There should be a dixv symbol on the front of the player. Burn the avi's to CD or DVD using program that came with your burner (probably Nero). and you should be able to play the disc in the DVD player. I also don't own this type of DVD player, either. Perhaps someone else can confirm this.
