I have been unable to add mp4 files, ripped from DVDs with the program "Ripit", to the itunes 9.1 movie library on my Macbook Pro running OS 10.6.3. . I have tried dragging and dropping the file to the itunes movie window. The file has a green + sign as I am dragging it, but nothing shows up in the movie window.  I have tried adding it to the movie library with the "add to library" command-no luck.I have done as the "Ripit" tech support suggested, which was to option click the file, and set it to "open with itunes", although I'm not sure how this actually helps to import it into the itunes movie library.  Suggestions?
Thanks

Have you put tags on the files, so that there's something (Title, etc.) that would show up in the iTunes library after you imported them?

Hello,

I would also update your version of iTunes to the latest version, 9.2

Thanks-for the comments.  I had not added tags at the time that the fiiles were created-is there a way to do it after the fact?
I'm a Windows guy, so I'm not sure how to do it on your Mac, but there has to be a way.

I found a solution.  I changed the extension from .mp4 to .m4v and this allowed importing to itunes. One can do this just by highlighting the name and changing the extension by typing in .m4v.  Then you can go to itunes and click add to library and using browser, select what you'd like to import from items with this extension.Thank you. I would consider this problem closed.

Can you play this file now on your phone (whenever you wanted)?

You are right.

"... MP4 and M4V files use the same codecs, which means that they are basically the same file type. Due to this, it is possible to change an MP4 file to an M4V file simply by changing the file extension."
