Yes, that could be it as I also had other programs open when I was doing the video stuff, from now on, I will close anything that is not related to video, thnaks.
My specs's are
Dell Dimension 3000
2.4Ghz 512Ram 200GB HD Leadtek Card
so you guys can see that my system is not specially designed to handle video stuff but as long as I only run the video stuff alone, I shouldn't have any problems, will test some more, really appreciate the help guys!!
