Hey guys,

I had a load of avi files which I have successfully converted to MP4's using Videora. These seem to play fine within iTunes itself.

However, when I come to sync iTunes to my 5th Gen iPod is says that the files cannot be played on my iPod.

Now i've already done a bit of research and it seems that although the files have been converted ok, the correct 'atom' wasn't added to the files during conversion which tells iTunes that the file is compatible with a 5th gen and below iPod.

Apparantly this can be rectified by using a piece of software called nicmp4box. However, in order to do this you have to type in various comand lines etc to to be honest I have had zero luck in doing it!!

Has anyone had any experience of this and could give me a quick step by step walkthrough?

Cheers

If you've still got the originals why not just convert them properly to start with?

make sure in finder / explorer that the file extension is present - ie .mp4

ive found if they havent got the mp4 extension, they wont play on ipod.

That's not the problem, just because it is an mp4 that doesn't mean it will play on every mp4 compatible device. When these files were converted they were seemingly converted in such a way that they aren't compatible with an iPod, or at least weren't identifiable by the iPod as being compatible. Technically speaking the data with an avi could be playable by an iPod, it's just the wrapper that is incompatible, in much the same way an atom contains information which can determine what a file can play on.
