Yep, that's the quickest way to get through the 100 hours and doesn't hurt anything. Just make sure the slide show is running properly (check on it a couple times) and you're good to go.
I couldn't wait personally, so I'm just running the slides while at work, doing other stuff at home and while asleep so I can still enjoy it in the mean time (just sticking to full screen content and limiting static logos etc. until done with the 100 hours). Should hit the mark this weekend sometime.
