How can I change an objects settings to render correctly when using the blender renderer I am sorry if this turns out to be a really basic answer. I have tried google searching the problem, as well as search through the first 3 pages of results here, but no dice.  

Here is the situation, I downloaded model from blendswap to append to a model of mine. My model was set up to use with blender's rendering system, the blendswap file on the other hand uses the cycles render. When using the blender render, these objects are transparent and prevent objects behind them from being rendered as well.

So, as a restatement of my question, how can I change an objects settings to render correctly when using the blender renderer, instead of exclusively the cycles renderer.  

Thanks in advance
Cycles Materials aren't compatible with Blender internal renderer engine, so you'll have to create new materials.
