Hi,
there are 2 different questions involved:
1.: scaling
2.: encoding
ad 1.:
Scaling is rocket science!
But MPEG Streamclip delivers the best software scaling I have discovered so far.
And I have tested ALL solutions over the last year from freeware to ultra high-end.
('best' according to the definition 'maximum sharpness at minimum aliasing')
ad 2.:
I assume you are working on OSX (M100), so you need to use Episode or at least Flip4Mac to encode *.wmv
When you got best results in MPEG Streamclip I assume you had used Flip4Mac? Since it is a quicktime component it is irrelevant what quicktime capable application you use to encode. The question is how your chosen application handles pre-processing (de-interlacing, scaling, etc.)
Now to answer your question:
The player application will do all the required scaling for you in realtime (=quick&dirty) to deliver a correct image through VGA
So simply scale and encode 3 versions with MPEG Streamclip ( 1080p; 720p; SD ) and test what resolution looks best and plays well on the laptops through your player application.
