Hey Walkerdbc,
Dvdsanta will join the 2 together for you as well as convert them to dvd for you, so once this is done all you have to do then is burn it and the program also does that for you as well...
There is a free demo version you can get with no time limits and it will do everything the full version does...It just has demo version printed at the top of the output video (but this can be over come by just zooming in)...I still use the demo version its very user friendly....It also has alot of other features as well...
This is the link to the site...
