George7, another important tip is, before you browse for the avi file to convert into vp6 using EA vp6 encoder, you should make sure that the file name has no space in it. For example, instead of "nba intro.avi" it should be "nbaintro.avi". I hope that helps.
Please don't double post. Edit your previous post if you have something to add.
We can't really answer a question like that, because we can't see your computer; we only have your word that you did everything absolutely right. To be absolutely sure of that, you'll need to describe exactly what you did at every step, so perhaps someone can pinpoint where the problem lies. Right now, there's not enough information for anyone to tell you what the problem is.
