The crux of the biscuit: Use the "consolidate" command in the edit menu to create one contiguous region. For added insurance, make sure these newly created contiguous regions have identical start locations. You may waste a little disk space, but your regions can then be brought into a DP session. NOTE: The "consolidate" command is not the same as the "bounce to disk" command. Automation, plug-ins, ... will be ignored. The command simply merges several regions into one. If you want to preserve automation, efx, and the like, you'll first need to use "bouce to disk" in PT.
