Import video to flash-->Error

[Flash Gordon]

I have searched these forms and so far what i have gathered. I just choose "import to library" and then choose what movie i want to import to flash. Well, i can't even get this far when i choose a movie Flash gives this this error message: "One or more files were not imported because there were problems reading them." The title of that box reads Flash MX but i am using Flash MX 2004. I don't know if that has something to do with it or not.
Thanks guys for the help.

ps. i have also read several post about these in the forums, i still don't understand. Also, there isn't a tutorial in the "tuts" section, which might be a good idea if someone wants to write one. If anyone has a tutorial to point me to that would be great.

I can't even get the dialogue box that says after i click import that say "Embed video in Macromedia Flash Document". What the heck?

Edit: I think i am making progress. Thought that flash would accept .mov and .avi extentions but now i think it will ONLY take .flv. If this is true, how the foo-dinkle do i get an .flv file?

I appoligize for being such a noob about this, but i would like to learn. Everytning i have seen so far deals with issues once you already get the movie imported, I can't even get that far. So if anyone has any info they would like to share or a link, ANYTHING--I'm desperate here--I would appreciate it very much.
Sorry for the bump.
