Sounds a lot like the movie files you downloaded are bogus or fake movie files.
How do you know that these files are genuine?
There is nothing wrong or different about Vista. I not long ago bought a new Toshiba laptop (top of the line) with Vista Ultimate and I couldn't be happier with the way it is running on my machine. You just have to make sure you've got a reputable antivirus application and make sure it keeps its virus definitions up to date and you shouldn't have that much trouble with Vista. Any operating system is only as good as the amoount of maintainence you put into it. If you go downloading movie files from here and there without being sure they are genuine is not Vista's fault. What else has happened that makes you feel so negative about Windows Vista? Incidentally what made you think that using Bold print would get you more notice than anybody else. You're no more special than any of the other people who post their problems here. What makes you think that using bold print makes you so special?
