Episodic DVD (to DVD-R).. isn't working.

I'm backing up X-Files Season 1 disc 2.. The 'multipgc.chp' file came up with all dummy files but Ifoupdate also created 4 separate Maestro.chp files---1 for each episode on the DVD.. How do I import these into Maestro--it accepted the dmmy .chp file (0 chapters) but not the 4 individual .chp files for each episode.. ??

I want to keep ALL original menus and extras... thanks!

Edit: Nothing's working.. I attempted 'playlists' but haven't a clue what I'm doing.. I read 1 guide and some threads.. but it ain't happenin.. Appreciate some help...
