So, about the differences. I couldn't get far into the game but :

Mtv Games logo, then Harmonix logo, then EA logo

http://redump.org/disc/83472/ intro sequence is :
Harmonix logo, then Mad Catz Interactive logo

So I think "Rev 1" should be changed to "Rerelease", like for Quake 4.

From wikipedia : "After the dissolution of MTV Games, MadCatz took over the publication and distribution rights for the game. They re-released the game in several promotional instrument bundles in November 2011, including one featuring the Fender Mustang Pro-Guitar controller. All of the bundles included access to five downloadable tracks with Pro mode."
