This may or may not have been beaten up in the past but I've been trying to accomplish this for some time and I still haven't found the device to do it. Well I take that back a little, I am sure a SlingBox HD Pro box will do this and if this would be the only device to use then that is fine but I am wondering if there are other options. The problem I am coming across is that most devices only allow for "open air" channels or basic cable non digital or pay channel type channels. Are there any devices out that allow the use of a DirecTV "cable card" to unlock the channels to be viewed over the mac? Also how good is the quality for the SlingBox HD or how would you compare it to anything else on the market if any? Appreciate any info guys.
