По-моему, хрень. Придётся фигле одно и то же с женой смотреть всегда -)

Can the home viewer watch a different channel than the remote viewer?
No. If the remote viewer is accessing a Slingbox connected to the set-top box that's being used by the home viewer, they must both watch the same programming. The only way that a home and remote viewer can watch different channels is if the Slingbox is connected to a set-top box that's not being used by the home viewer. Some Sling fans connect their Slingbox to a secondary set-top box that isn't watched as often at home.
