So I think they are both using a common ground.

Sounds like your hook up is correct.
If I am reading the comment by Manoel and your response correctly, I have to assume you are injecting a 5vp-p signal running from +2.5 to - 2.5 vdc. If so, I would say you have a -2.5vdc off set. This could work if the electronics in the mini-rc consider anything above 2.4 vdc a high. But my guess is it won't. It probably needs something closer to 4.5vdc to be considered a high.
Is there a way to adjust the offset to 0vdc? That way your signal will be running from 5vdc to 0vdc. Therefore, the mini-rc will see a high of greater than 4.5 vdc and a low of less than .5 vdc. Both should be good values for high and low.
