video advice

Another question asked of the sage was:

I have some Quicktime .mov files which I want to stitch together. What software can I use? I run XP...

First recommended Windows Movie Maker as being bundled with XP. But it cannot open mov files, of course. Then lent out an old copy of Ulead VideoStudio ver 3 which had come bundled with an old ATI video card (circa 1999-2000, which says it will not work with Windows NT!) Hope it worked. If not, convert mov to avi with MOV2AVI or Rad video tools or something like that...
