Thanks Doug, good to know.....just phoned Hauppauge Support and got the  
low down on what chip is inside what card:

North America:
WinTV Go (mono), WinTV Go FM (stereo, FM radio), WinTV Go plus (stereo,  
remote) all have BT878 chips for sure (for now).
WinTV Radio (stereo, FM, remote) has had the CX881 chip for about the  
last 6 months (which is what I had)

All cards have CX881 chip as far as this tech support guy could make  

BTW. I was lucky enough and my supplier is swapping all four cards for  
me (thank god for that :-)). So the question will be what happens to  
WinTV Go cards in the future.....yikes, I think I'll 4 more as spares  

BTW2 BT8xx works flawlessly under FC2 (and Suse 9.1 and 9.2 using FC2
