Belfast was one of the first places to be offered the Samsung boxes, but I suppose since the BB upgrades happened, supply over here has divebombed.
Anyway - on with answering your question.
I havent been able to remove the splitter thus having one of two boxes connected - would have to move the Widescreen TV, DVD player, NTL STB (all in a TV stand, which is on top of a fireplace shelf/sideboard). All in all it would be to much hassle to move it just to test the system. Sorry.

PS: Just powered up the STB again - goes immediately to "PACE" and sticks there (with the bottom LED illuminated ["Messages", I think it says beside it])
