I'm not sure if the animation is controlled from the OAM file output options. Would the expected behavior be to replay on page load? Or is the animation set to run once (or continuously, like a GIF would)? You might also be able to create a movie or image sequence in Photoshop to place into InDesign and export with in5.
If you'd like to send your InDesign and the output files to us, we can take a look for you. Send to support@ajarproductions.com (or list publicly here in the Answer Exchange). Note that files bigger than 20MB will need to be sent via dropbox or wetransfer, etc.
