RadRotator version 2.x is from 2006 and it is not compatible with the new browsers versions and MVC. I suggest to use RadRotator for ASP.NET AJAX for this purpose.
P.S. You can find components(Grid,Calendar,PanelBar,TabStrip etc.), which are built on top of ASP.NET MVC in our new suite - Telerik Extensions for ASP.NET MVC suite
