I've been having the subject problems ever since I bought the 500. I see a lot of similar posts throughout this forum. There are no solutions, only sophomoric suggestions by the "tech support" people, and a continuing of all the failures.
I'm not permitted to escalate my problems to someone who perhaps knows how to zero in on the causes. Moreover, I'm not saying the problems are the fault of Slingbox, but can't someone, with an in-depth understanding of how to determine where a problem lies, step up and help to make things right?
