Burn 2 single layer to one double layer

[perzaklie]

I have two single layer with 43 titles each. Is there any way I can burn them to one double layer without loosing my title structure?

Hi!

If there are no menus to be retained, you can use the "Join" function of either DVD2One or DVD95Copy (and probably other similar programs)

Thanks but they are instructional DVDs and both have extensive menus that I must retain.

Thanks but they are instructional DVDs and both have extensive menus that I must retain.May I ask then, what necessitates joining them onto one significantly costlier D/L disc, rather than simply copying them to two single layer discs?
