Hi there, It could be a .prj file problem, apparently arc can sometimes write .prj without a TOWGS84 tag, which confuses OGR, and hence confuses QGIS. For instance see: http://lists.osgeo.org/pipermail/qgis-user/2012-March/015993.html
In master, OGR has been compiled to take a best guess and appropriate EPSG. In the meantime, on of the settings that I change straight up on my QGIS installs is Settings -> Options -> CRS tab -> "Prompt for CRS" Which makes QGIS ask if it's not sure what the projection for a layer is. Hope that is of some help. -ramon.
