The main issue is that the Samsung SMT-3110 box is not included on the supported devices list. We can recommend you to use a similar model number from the same manufacturer or check the following thread, provided by alanrichey42.
I have SMT H3110, this is a very common Virgin Box. Surely you guys need to offer support for this?! WHat's the plan?
I have just spent hours setting up (and bought the SLingbox!) what is the best Samsung to select if I can't select this one for the remote? Any tips of getting the best out of it?
I have just setup my Samsung V+ box model SMT-H3110 , and while it doesn't have a remote under that number i did find that if you put in to the remote section TELEWEST ( make ) and TV DRIVE ( model ) you will get the remote that looks exactly the same as the V+ remote and works exactly the same. Only difference is the v+ button says tv drive .. But it works perfectly....
