Hi Jacob,

In order to use Slingbox to control anything external, it must have a compatible remote control code built into the player. In your case, you want to use it to control the Snapstream, not the cable box (if I read your question right). I haven't heard anyone specifically mention they've used a Slingbox with Beyond TV before, but there are some folks over at the SlingCommunity that have found ways to make their own remotes if the Slingbox doesn't have a compatible code set. 

Check out the forums and some of the articles at SlingCommunity.com. If there's any chance you could find someone to give you a hand, that's probably your best shot. At the very least, you may be able to find a Slingbox owner that can give you a definitive answer on Beyond TV compatibility.

Best of luck to you. 

Slingbox is only controllable through SlingPlayer, but unless you're trying to change the channel on the internal tuner on the Tuner, Classic, and PRO models, you're not really controlling the Slingbox.

Slingbox, when connected to a cable box, serves as an intermediary between the two. Hitting a button on the virtual SlingPlayer remote control sends IR commands to the cable box. In essense, if Snapstream can control your cable box, you don't need SlingPlayer to do it.

Maybe I'm missing what you're trying to do? Can you elaborate a little on your goal? 

Are you opposed to getting a wireless IR solution? They're not all that expensive, and would probably solve your problem. I was just talking to someone over on TechLore about them. Check it out: http://www.techlore.com/forum/thread/...
