Well one possible explanation is that there's something different that 
ivtv is doing to its modules that pvrusb2 is not doing.  Another 
explanation is that the PVR-150 hardware is different - there could be a 
different tuner module there, it might be using a cx25840 instead of the 
msp3400+saa7115 combo on your PVR-USB2 device.  (You might have 
mentioned that before and I'm forgetting...)
