I'm generally not much into adding too many effects and whatnot; I'm more interested in a program that won't crash all the time (like WMM tends to do) and that can allow me to tweak aspect ratio.

It's more likely I'll be able to get ahold of Adobe Premiere Elements (which, if past Photoshop nomenclature and my bit of research holds, means it's a more limited version of the Pro line), which I'm hoping will be able to at least do that much.
