PNG renders transparent background?

I have the background color set to white but when I render as .png's (for later sequencing in mplayer) the background of all the png files is transparent, how do I turn this off? I cant seem to find an option anywhere. Note: Preview and Render show the background, Export Animation doesnt.
Second Note: To sequence them in linux use a command like: mencoder mf://*.png on:fps=24 -o output.avi -ovc lavc -lavcopts vbitrate=400:vhq

Change vbitrate (variable bitrate) as necessary, depending on how complex the detail is.

Third Note: While typing this I managed to come up with a workaround by making a new layer with a white rectangle that takes up the entire screen and is the bottom most layer.

My test turned out the same... but I think your workaround is solid solution to the problem... if it is a problem.

I have exactly the opposite problem! I can't get my background to be transparent!

That the PNG sequence export delivers a transparent background is a normal behavior. PSD sequence export has that same property, I believe.

It offers the possibility to add a background externally. You can reuse a PNG sequence with different backgrounds or combine several PNG sequences and have different scenes with a limited number of animation clips.

So, in fact, you can save time if you use the transparency of the background to your advantage.

I think CinePaint is an excellent program for doing these kinds of manipulations. And as so many open source projects, it is freeware.
