Welcome to the Den.
if you were to really want to merge them, "DVD Lab" will do it, but you should know that, when you burn a DVD, the vob files can't be any larger than 1GB for standalone players to read them. That's why most authors set their programs to create vobs around 0.99GB in size.
When you go to play them, if you use a DVD player application instead of windows media player (as suggested above), it will emulate a stand-alone player.
All the DVDs you get here should be compliant with the standards and ready to burn, so they should be ready to play with the DVD player software. The DVD PLayer software will treat the files as a single disc, automatically switching between them when needed, just like a stand-alone DVD player does.
Hope that clears it up for you.
