I have a Slingbox Pro HD. Haven't used it in a month or so. Worked fine last time on the computer, iPad, and iPhone. Tried to use it on the road yesterday and only got audio. Got home and did some troubleshooting and still can't stream video, but audio works on all devices. The Slingbox is hooked up to a DirecTV HR24-100 receiver via component video and the receiver is hooked up to my HDTV via HDMI. As I said before, everything worked fine for years before this most recent try. During troubleshooting, I reset my DirecTV receiver, switched through all resolutions, reset and re-setup the Slingbox, changed component cables, tried it with the HDMI cable disconnected, and tried an S-Video cable, all to no avail. Any other suggestions or fixes?
