Hey guys... I found another post where someone was having the same issue ( https://community.sling.com/ideas/1065 )... this is my post from that thread after much frustration this afternoon. This is me trying to create a ''custom remote":
Okay... I can't stand working with this thing anymore. This is what I've been through today:
Step 1. Tried to execute on my Macbook Pro and I'm informed it's not compatible. (Come on guys) I have a laptop running XP so I go and grab that. Discouraging but not the end of the world... let's get this thing working!
Step 2. Firefox on Windows XP laptop
Attempt 1. I tried to execute the remotes setup and was told it wasn't compatible with version Firefox version 4. (Seriously Slingbox?!) So I had to downgrade from version 4.0.1 to 3.6.17. Okay... that's complete... let's proceed.
Attempt 2. The WebGUI went to 'not responding' after I clicked the first button requested in the 'create remote' setup (the power button). I waited 5 minutes and nothing happened. I couldn't click back or any of the other steps in the setup.
Attempt 3 and beyond... After closing firefox by killing the process I then couldn't get past the 'create remote' screen. Ugh.
Step 3. IE on Windows XP laptop
IE wouldn't even run the slingbox webGUI past the first step... when it went to the second step (the step for me to select my slingbox) it errored out saying that "Internet Explorer has closed the webpage to help protect your computer". IE says to go to the control panel, and disable 'Data Execution Prevention' and then restart for it to take effect to move on. Keep in mind that my security settings have not been manipulated in any way whatsover from the defaults.
Restarting laptop... At this point I've spent a significant about of time on this and I'm ready ready for the Slingbox developers to collectively push each other in to a meat grinder.
The settings change didn't work... same issue... googled and found this.. https://community.sling.com/message/42150. I made those changes, still having the same issue.
Step 4. Let's go back to Firefox?
Went back to firefox and cleared my cookies and history. I was able to get to the next screen on the WebUI. I tried to edit the remote I had created already, this didn't work (of course). I created a new remote and started again. Clicked the power button, this time it read correctly and took me to the next step, the pause button. I clicked the pause button, it appeared to read... and then I'm stuck at an hourglass again. Waited 10 minutes. This is unbelievable at this point. I kill the firefox.exe process. Trying again.
I'm back at the 'choose device' screen... it says 'your device is busy, would you like to take control of the stream?' I click yes... and... nothing happens (of course, yet again). I have to kill firefox.exe yet again. At this point I've wasted the better part of an afternoon doing a job that the Slingbox developers should have done for me... create a remote for this device. I'm fed up. If Slingbox wants to create a remote for this thing (even a custom remote, I don't care) I'll keep this thing. Otherwise it's going back in the box and back to the store. This is unacceptable.
