I’ve been looking on this forum and if this problem is covered in another post, if you could point me in that direction that would be great. If you have an answer to this problem that would also be great.

We build classroom presentations in InDesign and export them to PDF for final output. We use Acrobat Professional to place the videos, audio, buttons etc. Everything is currently done in Acrobat 6.0.2.

We place the videos (not embedded) and play them with the built in player as the preference. We place .mpg movies that are H.264

We have not had an issue with videos playing in various versions of Acrobat until Acrobat 9 came out. Our two most recent programs are having playback issues with Acrobat 9 but previous programs that were built the same way are running fine.

We have switched up to InDesign CS4 from CS1. I have rebuilt part of a presentation in CS1 from the ground up but still have a playback problem in Acrobat 9 and Acrobat 9 with the small updates.

Our classroom presentations are broken down into modules and are built with multiple PDF files, one for each modules. It starts with a tile screen and moving through a few files with buttons built in Acrobat you get to the various modules.

Here are the playback issues.

When we start from the title screen and use the links when we arrive at a video and click on the video it doesn’t play. If you then go to another module (different PDF file) and then back to the previous module (PDF file you were just at) and click on the video it will play.

I then tested just opening the direct module that contains a video. If you open the PDF directly and click on the video it will then play.

To do some further testing, with one of the modules containing a video, I removed all buttons in that file. When you then start from the title screen and navigate to the PDF file with a movie and click on it, it will then play. To follow-up on that test, I then added one button, navigated in from the title screen and then the video would not play.

Each time I did a new test, I shut Acrobat down and started it fresh.

If I did a test and got the video to play each of the following videos, in other PDF files would then play without any problem.

Our classroom presentation are set in full screen mode with the video as a floating window. I did test it out of full screen mode, and the same symptoms happen for each scenario.

Again, our previous 80+ programs are working fine, which makes me think there is something in CS4 that I am missing, but when I rebuilt part of on in CS1 it still had the same issues.

Our material is built on Mac and in class run on both Mac and Windows machines. The video play back problem happens on both Mac and Windows machines.

If I run it on Acrobat 7 or 8, everything works fine.

We will be authoring on a newer version in the future, but currently I’m trying to solve this problem on the video playback in Acrobat 9 (with minor updates).

If anyone has any insight into this issue please post a response.

Thanks in advance for any help.
