I upgraded to a new workstation and was able to transfer all my apps with one exception, MediaMover. I have the installer and the serial number but not the activation code. Since Random Video is no longer and Digital River does not have the code, I seem to be stuck. Has anyone solved this problem? 

Sorry, no. But ages ago I started using the excellent and FREE utility MDV. It's available for both Mac and PC and does largely the same thing. You can find it here:

Switch to a donation based program MDV  (check out this thread)

It was originally developed for Windows systems and I switched from Media Mover to it when it was first released. By then Random Video had seemed to have lost interest in his product.

The PC version has not been updated since 2008 but is still IMO better than Media Mover.
You can find downloads for it here.  For some long forgotten reason I did not update to the 2008 release. I was happy staying with the June 2007 release and have used it, at least, weekly from then to now.

Another happy user of MDV here too.  Like Andrew, I also briefly used Media Mover, even providing direct feedback to the dev.  MDV is better in my opinion.  I no longer even own a functioning copy of Media Mover.

Thanks, all. I tried it and you're right! Very straight forward.

Unfortunately development of MDV is only Mac, the PC version being abandoned; maybe we should all ask to the developer for a new release, to port all of the Mac improvements.

I'm in the same boat. Just recently built a new system and MediaMover won't activate.

I used MDV for years and another freeware app before that, but switched to MediaMover since development of MDV seemed to be at a standstill. And I was also suspicious that it didn't always catch all the media in a project.

I actually really liked MediaMover because of its "move offline" feature which moved all the media from a project into its own folder and even the Avid mediafiles subfolders were kept. This made archiving really simple.

There are some more professional level tools such as Marquis Broadcast Project Parking which would be fantastic for a large post production house with shared storage and such...but costs 1000's of dollars to license. Even their "Solo Parking" costs around $500 to license.

What I've never been able to understand is why Avid just doesn't build their own utility that makes archiving projects a simple process.
