There's VST plugins for DAWs that can do upmixing from stereo, I personally used Halo Upmix by NUGEN. It's quite robust and supports up to 7.1.4. I haven't tested it for things like Dolby Stereo decoding but considering it doesn't have LCRS layout I don't think it would be much better than FreeSurround.
