You can't really predict the size a bitmap will take in vidmem as internal card memory alignment etc. kan eat some.
And as mentioned, conversion might occur in other layers such as DX and OpenGL
The best thing to do is to load the texture and check the vidmem again. Actually the vidmem is probably directly returned from DirectX in Blitz3D and the docs says it's not all that reliable :)
