hi Pontus,
It's worth noting (and a read through the forum) that PD7, whilst being a great editing and producing program, is not the most sophisticated authoring and burning program, and many people opt to use other programs at that stage of the process.
To combine projects is a 2 (or maybe more) stage process. Firstly, decide on your sub-project, say 1 event/party/trip whatever out of several and then edit and produce this as a 'finished' video say as an mpeg2/avi or whatever. That is one pds file and can be kept as such, re-edited, archived etc.
Edit and produce to file your other sub-projects in a similar way. You now have several separate pds files and several 'finished' sub-project videos.
Your final pds project is to import the sub-project videos into a new pds project, do your final editing etc on the compilation and then either produce a final video to file or burn a DVD to a folder (for using another burning program)or direct to disc.
Personally, I use another DVD authoring program at this stage but that's often because I want a more spohisticated menu handling system that copes with different videos rather than just chapters in one video as in PD.
Hope that helps.
