Anyone know if I can connect the Slingbox 500 at my parent's house (where they have Cox cable but not internet), and control their TV for them from my house in another state (of course, I have internet). ?? This could be a major use for many of us whose parents can no longer deal with complex TV remote devices.
I see you stated that there is no internet connection a you parents house, unfortunately in order for your situation to work you would need an internet connection on both ends. Below are some helpful links;
