Hi Wowiegurl,
The problem is not only on the latest release

the problem has been there since the 1st release of Moviestacker.
That's maybe why Karl removed both from download.
So either you find it somewhere else or you'll have to settle with FitCD for a while as Muaddib is going to need a long time to remove the GPL source code for the next release of Moviestacker.
Of course you'll tell me that FitCD is very poor in terms of available plugins/filters but that's why Moviestacker was born in the 1st place...
Anyway, FitCD will at least give you the correct resizing figures you need in you avisynth script

.
Cheers
