I bought a slingbox from a friend and its the Pro HD, red one( 2009), When I hook it up it will show the remote and the remote works on my computer but it only shows a blank screen or black/dark gray window with the controls and everything on it???? We only have old TV hooked up to Scientofic Atlanta cable boxes one is the Explorer 3000 and 3200 with the UR5U-8700-AB remotes. Do I have to disable anything or if the TVs are old analog ones does that matter? how about 64 bit internet explorer? how do you put it in 32 bit mode?
