Time will tell, but doing a hard reset to revert to factory settings seems to have solved the problem for now. It looks like a Slingbox software update did not install properly - probably due to internet connection issues. There is a good article at Slingbox support on resetting your box. Configuring your box after reset is all done with your SB remote!
While watching TV, my SlingBox starts up and overtakes my cable TV signal on the TV. After about a minute my cable feed comes back...???
Any ideas why it does this? It started about 3 weeks ago. Never had this happen before. There is no real pattern as to when it happens. Sometimes it does it 2-3 times an hour, some days not at all.
