Hi L Thanks for the response

The files may have DRM protection interfering with playback.

MM4 1830
Windows 7pro

iTunes tracks are supposed to be DRM free now but that may not be actually true.

Which version of MediaMonkey and Windows?

The files may have DRM protection interfering with playback.

When I have to go through the horror of buying tracks on Itunes because I am in Canada and Amazon is blocked from selling MP3s here, I suffer for an hour installing Itunes, logging in, buying the tracks, and then removing Itunes ...... in the end I get M4a music files.

I usually just convert them to MP3 because raw tagged Itunes M4a files randomly just don't play in MM4. MP3s never do this.

I happens maybe 1 in 40 attempts to play a M4a, and generates a "Codec not Found" error message. I can click on that exact same track 1 second later and it plays perfectly.

I did at one time have the codec pack installed but I removed it a long time ago.

It would be nice to just leave them in their native format.
