I've been trying for the last 4 hours to get slides to transition when I want them to, which is how I recorded them. I've already gone through microsoft help to verify I'm doing everything the way I should, and I've also even looked at a youtube video to see if they did anything different. No dice...

So, I have video and audio playing on most slides. I hit that record slide button and started it up, going through each with the timing I want. I then viewed the slides with the slide sorter to verify that the timings for each slide are correct. They are.
I then very-verified by looking at each slide's transition page, seeing that the slides avance only after a set time, which populated with the time set when I recorded the show.

So, then I preview the slides from the beginning and...it lags for a good 2 minutes after the first slide, which is read to only last 9 seconds before transition. This happens with each subsequent slide...but it's stranger. The next slides all hang for the 2-3 minutes before starting. The videos embedded and audio embedded are all set to start automatically and immediately upon the slide transition.

There are no additional recorded presentations on top of the one I'm expecting.
