I upgraded from PP2007 to PP2010.



I continued working on a presentation from 2007 and it was fine. Of course when I saved, it saved to 2010.

Two days ago, I made a video on Windows Movie Maker (2007). Saved it as a movie and inserted it into my presentation.

That was the end of my life as I had known it to that date.

The video wouldn't play.

I did the Google thing and found I was not alone.

I tried converting the video to different formats with a good conversion program (Format Factory). Nada.

The video plays fine in Windows Media Player.

In the "Save as" option for saving the presentation, there are many formats, but no PP 2010.

I reloaded PP 2007, but of course, it won't play the 2010 version.

As the line from "War Games" goes: "Right now, I'd piss on a spark plug it I thought it would do any good."

Any help (in single syllable words) will be appreciated.

Thanks.

2010 uses the DirectShow dll to play video. The problem is that other third party apps can also use / abuse Direct Show and cause it to fail in PowerPoint.

It's not possible to say which app might be doing this but I would suspect

Video / image Converters
DVD writers
Graphics editors
especially ones that come free with your PC.

Try to stop them running at start up and see if that works.
