It depends on how you saved your projects. PDR project files (.pds) simply contain a set of instructions for PDR to follow such as what files, where they are, what to do with them, what effects to use etc.etc. If you have the instructions i.e. the .pds and not the files it won't work.

PDR has an option to "Pack Project" and if you used this then you have everything you need in one place and can work with just that once you have installed PDR16 (PDR15 won't 'understand' the PDR16 projects).

If you have the .pds and all the assets (the video, images, audio files & any special tansitions etc.) then you can still open the project and PDR will first tell you, one by one about the assets it cannot find. In each case you can then 'tell' PDR where the assets are and once that is completed the project should work as before on the new computer.

Thank you for your very timely repy!

If I go and "Pack" all of my projects on my PD15, then upgrade to PD16, then I will be able to open them but not change or burn any other copies of them? Or is it just to enable it to understand a different set of instructons to open in another PD version?

I do have all of the files etc.

I appreciate your patience as well as your help.

The scenario that you described as I understand it is projects done on one computer in PDR16 being moved to a computer currently with PDR15 but about to be upgraded to PDR16. Once PDR16 is installed on the second computer it should be possible to open projects done on that computer in PDR15 without any need to do anything else.

Thanks very much. I have been "Packing" my projects and will then upgrade. Appreciate your help.
