Any video editing software with own codecs? I just tried the new Lightworks and even though I followed the installation instructions rigorously I managed to hit codec problems. 

Is there any (preferably proprietary) video editing software with own codecs so that it would run on any Windows? I just want the software to work. Preferably without crashing.
I installed Sony Vegas Movie Studio HD ($34). The download took half a minute, the same to install it, no prerequisities ( except the software updated windows installer ) and everything worked and has been working like a charm.
