I use Paint.Net to make backgrounds JPG's transparent then save it as PNG.  When I add the picture to the movie project it correctly displays as a transparent background.  However when I save it as a movie file then play it, the older version of the picture with the non-transparent background is there.

This doesn't happen to all pictures.  For example, I whipped up a drawing using Paint, saved it as PNG, made the background transparent, it works fine.  I find a JPG online, use Paint.Net to make the background transparent, then save as PNG - doesn't display correctly in MM.

Anyone know how to correctly get converted JPG's that are now PNG's to display correctly?

Thanks!
