Good Morning, While trying to convert files as described in my previous post I visited: http://forums.afterdawn.com/thread_view.cfm/48608 in order to get a comprehensive picture of the required codecs. Unfortunately I am stuck on step (1) listed below: STEP-BY-STEP CODECs 1. UNINSTALL ALL YOUR CODECS (DivX, Nimo, XviD, etc) I looked at this and said to myself, "How"? Then I though perhaps the best thing would be to ask. So I am asking since I have no idea where they are and what they are. OS: W2K SP4 Just a tad confused. F.
