I just received a Slingbox 500 and want to connect it to my Time Warner Cable box which is a Scientific Atlanta Explorer 8300HD Box. Currently I have it set up with an HDMI from the Cable box to the Slingbox along with component cables from the Cable box to the Slingbox and it is connected to my TV via an HDMI cable. While setting up the video input when attempting to use component I get a notification saying no video signal and when configuring through HDMI I receive a video signal for around .5 seconds and then a blank screen that says to use a different input than DVI or HDMI. Considering that Time Warner offers this product to people buying their top tier internet, I can't imagine that they would block their incoming signal to that same product. Anybody have any idea how I can fix this issue?
