If you can provide the model number, I will give you a direct link to the site where to download it.
I am trying to connect an HDMI cable directly to my 860 from a Direct TV HD DVR model HR21 receiver. On the Direct TV HDR, I have turned off output for signals below 720 resolution. When I connect I get a "Mode Not Supported" error message and no sound or picture.
If I send the signal through my AV Receiver first and use the same cable to connect out of the AV Receiver to the TV, everything works so I know that the cable works. I have read that Samsung has problems handshaking with certain TV boxes and am wondering if there is an update to the firmware or something else that I can do to allow the connection to work.
