I converted .mov files into .avi files with IMtoo MOV Converter 6. I then went to import them into my collections in Windows Moviemaker and the error message says the avi could not be imported the required codec was not downloaded automatically because the download codecs automatically check box is not selected in the options dialog box - but the three things that arein the dialog box are checked. They are Real Media Splitter 1.0.1.1, Microsoft DTV-DVD Audio Decoder 6.1.7140.0. I am thinking I may need to download a specific codec or is there a way to get these converted avi files to import into collections in my Moviemaker 2.6 for Windows 7 or is there a way to get the mov files in there?
