I mean, you've pretty much trouble shot the problem. If the Dish-box works w/o splitter but not with, then it tells you one thing. It's the splitter box. Now why it isn't working can't tell you. But I'd say it probably has something to do with the particular splitter box you are using. It isn't able to pass through something the dish box is trying to send. I'm not a video expect, but it's what my technical assumptions make me believe.
Did you try looking through the dish settings on the box and see if there is any option you need to turn on for this? Maybe try changing the output, to say like SD.
