I had exaclty the same doubt about the SR-X650. Also for this receivers there are 2 s/w versions: Super & Ultra. The SUPER version works on my receiver, no problem. But when I loaded it into a newer version of the same receiver model, it did not work. I suppose the ULTRA version refers to this newer version of the same receiver model. Indeed this newer version differs from the previous one because it's got an embedded CAM. |
