Photomerge 360 Pano stitch

I want to make a 360 degree (circular) panorama shot to convert to the QTVR. I have no trouble getting shots with sufficient overlap and using Photomerge to make a long panoramic shot, but what do I use to merge the "2 ends" together to make a 360 degree loop?

I was looking at cubiconverter to format the QTVR <http://www.clickheredesign.com.au/>.

But there is a missing link in my understanding of how this works and I'd appreciate your help.

Thanks,

Have you looked into VRWorx?
