no problem - I do this e.g. with xfiles series. there a 4 long titles & lots of little ones ( that you don't need)

So use customise mode & select only titles 1 & 2 + preserve menus
then repeat using only titles 3 & 4 + preserve menus for the 2nd copy.

you get the normal menu when you load each disc - offereing a choice of 4 episodes - but only 2 will actually work. the menu is in the IFO files not in the titles, so that gets copied anyway. JUst label your copies so you know what is actually on each !

If you untick preserve menus then I guess the 2 episodes would run back to back but I've not tried that.

for single episodes with no menus at all just use main movie option.

pathfinder will tidy things up further if you select remove warnings & jump to 1st menu or title, but pathfinder has trouble with some episodic discs & needs to be disabled to rip them.
