Thanks for using our Answers Forum. I understand that you are having video connection issues with your Slingbox Classic.
I would recommend upgrading at this point. The newer Slingboxes allow you to connect to your Slingbox using a wider variety of devices.
I have an article, Special Upgrade Program for Slingbox Owners that explains exactly how to upgrade your Slingbox.
Hope this helps.
