Need someone who knows Pinnacle Studio very well

Basically i have already created an hour long dvd of exactly what i want and it works fine etc... Now, what i want is to be able to choose whether you want to watch the 60 minute video or the 100 minute video. Bare with me for a sec, so you pop the dvd in and the first title screen allows you to choose 60 min clip or 100 min clip. when you choose the 60 min clip it goes to another screen where you can hit play or jump to 15, 30, 45 min intervals. however, when the 60 min is done it needs to loop back to the menu where you can choose 60 or 100 min clip. if you choose the 100 min clip it goes to a different title screen for that 100 min video with intervals and if you hit play all it will go through the entire dvd (first through the first 60 mins, then rest) for a total of 100 mins.

now i know how to make title screens etc... but what i am afraid of is when you click the 100 min clip, when it gets to 60 mins its just going to loop back because thats where you set the menu return link. any ideas?

edit*

just to clarify i know that the easiest way would be to make 2 different dvds but it would be really nice to have the choice on startup on a single dvd. i somehow need to tell the program that when the play button is click on the 60 minute title screen to stop after 60 minutes and loop back to the main menu...and if the play button is clicked on the 100 minute title screen to play through the entire dvd then loop back to main menu

i could setup a dummy title frame thats blank for 1 second that has the return to the menu for 60 min clip...and somehow have the movie skip that frame if the 100 minute link is clicked...don't know how to make that happen though
