I've inserted a video file in to PowerPoint 2010 - it's an mpeg video I made last night in Adobe Premiere Elements 9. The video plays fine in Windows Media Player on the same machine, but in PPT, plays only the first 30 seconds of audio.

The audio then cuts, but strangely, the video continues playing normally. Boringly, this happens in PPT 2010 on both my desktop and laptop.

Was wondering if anyone had experienced this or, particularly, fixed it?

Thanks in advance for any help...
