Thank-you for contacting Slingbox Forum. It would be wonderful to access other TVs in your home with the Slingbox!
At this time, we are not able to connect the Slingbox to a second TV in the home network except by connecting the computer you have to that TV.
There are connected devices available, like the Boxee Box and WD-TV, that will work with the Slingbox PRO-HD and the Slingbox SOLO and attach directly to you TV. They can be used with US-based Slingbox devices only at this time. More information about these devices can be found on slingbox.com and you can Google information about them too.
Hope this helps you with this issue!
Have a great day!

Only way (currently) seems to be to purchase a Slingcatcher from ebay or similar online place. Slingcatcher works very well in most circumstances. Great shame that Sling stopped making them for whatever reason. From reading this and other forums, none of the "boxes" currently sold (Logitech, WD etc) function reliably. Also do not work at all with Slingbox Pro (I understand).
It would be nice if Sling would comment on why they decided to stop producing the Slingcatcher, - and if they have plan to produce an updated version.
