Check you software to see if slingbox updated recently, as in March. They stopped supporting certain Cable/Dish resolutions as best I can tell. After years of the same cable box, I updated software, by force of Sling Media, now I have this issue. Total ****! never had this problem, nothing changed excpet the software "update"\
Now BOTH of my slingboxes show "unsupported signal"
Shame on Slingbox and tell everyone to speak out.
Hi Everyone - I have had a Slingbox 500 for a few years now. I recently moved the Slingbox from one location to another, and set everything up just as I had it previously. Now, when everything is hooked up, everything looks great on my TV when the Slingbox is off. However, as soon as I turn the Slingbox on and try to connect via the Slingbox website, the picture and sound appear momentarily on my computer, then I lose both picture and audio on the computer and the TV. So once the Slingbox is on, nothing works, neither the TV nor the Computer.
