First, thank you very much for really trying to help me through this for days now.
Second, the video is great and I am sure a lot of users here could benefit from it.
Third, unfortunately it just seems to be impossible for the nx500. The nx500 does not support tethered connection (only the nx1 does), and the nx500 has no setting for USB connection type (which you select "remote" on the nx1) and only functions in mass storage mode. Even if it could be hacked to allow remote usb connection, I am not sure the software would recognize the camera since samsung remote studio may be coded to only work with the NX1.
Again, thank you very much for your effort to help me. It is appreciated.
