To test our software products for Microsoft Windows Vista compatibility, DTLink
picked up an HP Pavilion Entertainment PC with Vista Home for real cheap.
On a lark, I've dumped the Deals' Gap video footage I took onto that laptop and have been putting together a movie using Windows Movie Maker. At the point where I was ready to burn a DVD with it, Windows DVD Maker would lock up cold saying there was a problem with DivX and that an upgrade might fix it. The download from the DivX site, on the other hand, tells you that Vista is not yet supported.
Googling around I found this comment to a blog post:http://blog.stevex.net/index.php/2006/11/23/windows-movie-maker-has-stopped-working/#comment-70845
Going to Tools->Options and looking at the list of filters I found that HP had installed a bunch of third party codecs. Unchecking them stopped Windows DVD Maker from locking up.
