How to merge or join divx Mac?

Hello fellows,
How to merge or join divx mac?
Is there a way that we can join or merge two or more movies in a divx movie player?
My mac operating system is not that easy to operate or manipulate so I be needing so much of your help for this.
Give me some instruction to be followed to get this done properly.
Thanks.
Regards,
Kristen James.
