How does an installed app use storage?

I'm building an app that will contain a fair amount of resources (video) and need to better understand the impact a large APK will have on users. As an experiment I located a 32MB APK (which contains lots of video) and installed it on a Nexus One. Before installation the phone showed 36MB free internal storage. After installation is showed 33MB (not the ~4MB I was expecting).

How has a 32MB app been installed in such a way that only 3MB of internal storage has been used?

If anyone can clarify or point me to a resource that explains how internal memory is used by installed app, that'd be great.

App is probably installed on external storage e.g. "moved" to flash memory card. Still some small amount of internal memory is used.

It's always good to enable "move to SD card" feature though app home widget will be disabled if app is moved to SD card.
