how are you going to get the video at the laptop?
do you know how the sligbox works?
1. the slingbox will be at home connected to your router.
2. the video output from DVD or Dishnetwork into the video/audio of the slingbox
3. with your laptop connected thru wireless card will have access to your home network that way, you would have access to control your video device. It is the coolest gatgets ever. I have my dish connected and I can watch live TV with full control.
