is there any soultions to acess my sling adapter on another tv my house that isn't conected to my 722k. do any internet boxes like roku or boxee etc support this.
Nope. Nothing smaller than a HTPC or laptop will work (other than the mobile clients you know about). I'm convinced Dish did this deliberately to drive traffic to their lousy DishOnline and thereby increase the chances that some weak-minded fool will pay good money to watch old movies ON THEIR PC.
why pay 200 for a slingbox when the adapter is 30 as long as I have a comatible box like 722k. how much will a media pc cost or should just get a netbook
