Just a final note to say that I put a 3.5mm jack into the HD Fury 111 with two phono plugs into the slingbox and all now working perfectly. Thanks to Alan Ritchie on here and also thanks to Darren Tulk at HD Fury for their invaluable assistance. It now all works fine, even from 8,000 miles away on a slow internet connection of ony 1 meg.
I have been trying to get my slingbox 350 linked to a Samsung BD-F7500. I got the HD Fury 111 converter today, fitted it with the default dip switch settings and got no joy - no video and no sound. I changed some dip switch settings as I guess the resolution was too much for sling. After the changes I got good video over the slingbox. In case anyone else has the same settings problems, this is what I did to get the video side to work (not all may be necessary by the way - I am not a teckie)
switch 1 leave as off
switch 2 leave as on
switch 3 leave as off
switch 4 switch to off
switch 5 leave off
switch 6 leave as on
switch 7 switch to off
switch 8 switch too off
Two problems left to resolve...no sound - does anyone know how I can get the sound to work ? There is an optical output from the HD Fury 111 but of course no optical input into the slingbox. I tried phono plugs from the Samsung direct to the slingbox but no joy there either.
Second problem is that the remote works (I just chose a standard Samsung BD remore as this model is not listed) but is very limited. I need the full remote for a Samsung BD-F7500 ? What the basic control is lacking is the ability to get back to the smart hub or you just get stuck remotely going down a path you can;t get back out of and back to main menu
