Wow ... glad to see so many responses to this issue. IMHO, requiring to watch sling box through an external website when I am at home is the most archaic and ridiculous connectivity method. To boot, I have NEVER been able to get sling box to work from my MAC browsers (Firefox & Safari, as we know Chrome is not supported). However, from the same internal network ALL of my mobile devices running the slingbox app work great .... unfortunately I don't like watching tv on my 6" iPhone!!!
come on Sling .... step up to the game, you need better support mechanisms and a better connectivity mechanism.
