As a follow up, finally got this working. read about it here. Conclusion was that it was either motherboard model/revision specific or just board specific as in only my mb but not another one of the same model.
We ended up using winamp's line-in plugin to get the radio into RR and it works flawlessly.
Now just trying to refine and simplify the RR radio skin in DFX as it has too many buttons and alot of them didn't work.
