They are involved. MPlayer uses avs scripts by (more or less) generation
in memory another avs file with e.g. this content
Import <your-original-avs-file>
ConvertToYV12

Since the MT documentation says it must be the first statement in the
file I'd guess it does not work like this.
You can easily test by creating such an avs file and see if VirtualDub
is also slow with it.
